Explanation:
True or False Gases do have a definite shape and volume.
Answer:
false
Explanation:
Answer:
False
Explanation:
It is false as the particles of gases keep moving. They have very weak molecular bonds. They are so weak that they can move freely anywhere and in any direction. Even if you trap some gases and a closed bottle, they keep moving. We can't measure what the shape is or what the volume is. Therefore, it is false.

help Me with the meanings PLEASE And the subject is science
Crust-In geology, the crust is the outermost solid shell of a rocky planet.
Mantle-A mantle is a layer inside a planetary body bounded below by a core and above by a crust.
Core-is the innermost part of the earth, comprised of the inner core, at the center of the earth, made of iron; and b) the outer core, which surrounds the inner core, made of iron and magma.
Lithosphere-rigid, rocky outer layer of the Earth, consisting of the crust and the solid outermost layer of the upper mantle.
Athenosphere-the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
Mesosphere-the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.
Sea floor spreading-the formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side.
Plate Tectonics- a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
Tectonic plates- A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. ... By contrast, oceanic crust is composed of basaltic rocks, which are much denser and heavier.
Convergent boundary- A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other causing a process known as subduction.
Divergent boundary- In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other.
Transform boundary- A transform fault or transform boundary is a fault along a plate boundary where the motion is predominantly horizontal.
Radioactive decay- a radioactive process in which a nucleus undergoes spontaneous transformation into one or more different nuclei and simultaneously emits radiation, loses electrons, or undergoes fission.
Subduction zone- Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle.
Continental drift- Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed.
Deformation- the action or process of changing in shape or distorting, especially through the application of pressure.
Folding- A fold is a bend in the rock strata. Folding: Is a type of earth movement resulting from the horizontal compression of rock layers by internal forces of the earth along plate boundaries.
Fault- A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. ... Earth scientists use the angle of the fault with respect to the surface (known as the dip) and the direction of slip along the fault to classify faults.
Shear stress- Shear stress is the stress component parallel to a given surface, such as a fault plane, that results from forces applied parallel to the surface or from remote forces transmitted through the surrounding rock.
Tension- in physics, tension is described as the pulling force transmitted axially by the means of a string, a cable, chain, or similar one-dimensional continuous object, or by each end of a rod, truss member
Compression- Compression, decrease in volume of any object or substance resulting from applied stress. Compression may be undergone by solids, liquids, and gases and by living systems.
Syncline- a trough or fold of stratified rock in which the strata slope upward from the axis.
Anticlines- an arch of stratified rock in which the layers bend downward in opposite directions from the crest.
Law of Universal Gravitation- Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Law of superposition- Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.
law of conservation of mass- The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Which statement best describes John Dalton's use of creativity in his work? He reinterpreted and retested Joseph Proust's results. He used a philosophy to conduct his experiment. He recorded his results as four parts of the atomic theory. He rejected Democritus's idea that matter was composed of atoms.
Answer: The correct statement is that,
'He reinterpreted and retested Joseph Proust's results'
Explanation:
John Dalton was an English chemist who contributed greatly to the field of Chemistry. He published his theory about atom in 1808.
Dalton was the first person to recognize a workable distinction between the fundamental particle of an element (atom) and that of a compound (molecule). The atomic theory generally summaries the laws of chemical composition which includes:
--> law of constant composition and
---> law of multiple proportions.
John Dalton was being creative in his work by reinterpretation and retesting of Joseph Proust's results. Joseph Proust was a French chemist that first discovered the law of constant composition in 1794. This means that many has started working on the atoms before John Dalton discovery.
From the previous works of Proust, he had studied tin oxides and found that their masses were either 88.1% tin and 11.9% oxygen or 78.7% tin and 21.3% oxygen (these were tin(II) oxide and tin dioxide respectively). Dalton retested and noted from these percentages that 100g of tin will combine either with 13.5g or 27g of oxygen; 13.5 and 27 form a ratio of
Dalton reinterpreted it by finding an atomic theory of matter that could elegantly explain this common pattern in chemistry – in the case of Proust’s tin oxides, one tin atom will combine with either one or two oxygen atoms. I hope this helps, thanks.

A.) He reinterpreted and retested Joseph Proust's results

The reaction for the combustion of acetylene is shown. Explain why this reaction is a redox reaction by identifying the oxidation numbers that change, what is oxidized, what is reduced, and what happens to the electrons during the reaction. 2C2H2 + 5O2 → 4CO2 + 2H2O
Answer:
2 C2H2 (g) + 5 O2 (g) → 4 CO2 (g) + 2 H2O (l)
Explanation:
Redox reaction: In this type of reaction, oxidation and reduction reaction occurs simultaneously in same chemical reaction.
2C_2H_2+5O_2\rightarrow 4CO_2 + 2H_2O2C
2
H
2
+5O
2
→4CO
2
+2H
2
O
This reaction is a redox reaction :
Removal of hydrogen or addition of oxygen is termed as oxidation. in above reaction, removal hydrogen from acetylene gives carbon-dioxide.
Removal of oxygen or addition of hydrogen is termed as reduction. in above reaction, removal of one oxygen atom from oxygen molecule with addition of two hydrogen atoms gives water
The oxidation number of carbon in acetylene is -2.
The oxidation number of carbon in carbon-dioxide= +4
Oxidation number of carbon increases after the reaction which means that carbon is getting oxidized.
The oxidation number of oxygen in oxygen gas = 0
The oxidation number of oxygen in water = -2
Oxidation number of oxygen decreases after the reaction which means that oxygen is getting reduced.
The electrons released during oxidation are transferred to the species which are undergoing reduction reaction.
Answer:
Just put this, or something like it:
The oxidation number of carbon changes from -1 to +4.
The oxidation number of oxygen changes from 0 to -2.
Carbon is oxidized.
Oxygen is reduced.
Electrons are transferred from carbon to oxygen.
