Answer:

If the chef is in a hurry we would assume he would want the pan to heat up so copper

Explanation:

Answer:

A. The chef should choose the copper pan.

Explanation:

Copper conducts heat well because its atoms contain only one free valence electrons in the outer shell. Elements with a low number of valence electrons transfer heat the best, and copper has only one. Valence electrons move about freely.

Good luck on your test (Or whatever it is) !!

When the temperature increases with an increase in pressure, it is a direct relationship.

Gay-Lussac's law can be described as when the volume of the gas remains constant then the pressure of a gas is directly proportional to the absolute temperature of the gas.

The mathematical equation of Gay Lussca's law is written as follows:

P/T = k

It can be represented as the pressure is directly proportional to the absolute temperature.

P ∝ T               (where 'V' volume of gas is constant)

or

[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2}[/tex]

Where P₁ and T₁ are the initial temperature and pressure while P₂ and T₂ are the final pressure and temperature of the gas.

The sample of gas has a fixed volume of gas and on increasing the temperature the gas molecules acquire more and more kinetic energy. So the pressure of the gas will also increase.

Therefore, there will be a direct relationship between temperature and pressure of gas.

ANSWER

The molarity =

molecularweight

density×purity×10

=

36.5

1.18×36.5×10

=11.8molar

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{8.50 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 14.119601...[/tex]

We have the final answer as

Answer:

preservation of raw materials

Explanation:

Reusing and recycling is the process by which the used products are used again or recycled in different form to use it again. Excessive use of the raw materials can lead to their extinction. Recycling the materials helps in decreasing the pollution in the environment. It also helps in reduction in the emission of the harmful gases. When municipal wastes are reused or recycled, the raw materials are preserved. These are the process involved in sustainable use of resources.

Number of feed = 555 pounds

Feed cost = $237.21

The main composition of algebraic expressions are:  

• 1. phrases/terms  

• 2. variable  

• 3. constants  

• 4. arithmetic operations  

• 5. coefficients  

• 6. exponent  

Initial weight = 82 pounds

Goal weight = 267 pounds

The difference in weight that must be achieved :

[tex]\tt 267-82=185~pounds[/tex]

The pig will gain 1 pound for every 3 pounds of feed⇒ 1 pound weight=3 pounds of feed

The amount of feed must be given:

[tex]\tt 185~pounds~weight\times 3~pounds~feed=555~pounds~of~feed[/tex]

Feed costs $21.37 per 50 pound bag, so for 555 pounds :

[tex]\tt (555~pounds\div 50)\times \$21.37=\$237.21[/tex]

Answer:

The flash of green light may give off some type of energy that only emits from green light which probably energizes the Flubber

Explanation:

A flubber is a rubber like polymer that absorbs and amplifies energy. A flubber absorbs energy from a light source and electrons present in it are excited in order to emit light of higher wavelength. The green light absorbed by the flubber to emit longer wavelength of light emitting more energy.

Answer:

So... for the element of PHOSPHORUS, you already know that the atomic number tells you the number of electrons. That means there are 15 electrons in a Phosphorus atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and five in shell three.

Explanation:

Interference trust me I just did this

A light wave bends to pass through a crack underneath a door, this represents interference. The correct option is option C.

Like other waves, light waves also transfer energy to a source. They are made up of tiny energy particles known as photons. While photons have no mass, they do have momentum and energy.

There are types of light waves which human eyes cannot perceive, just as there are noises that can't be recognized because they fall outside the range of human hearing. However, all forms of waves share characteristics like wavelength and frequency. Wavelength is the separation between neighboring wave components (e.g., crest to crest or trough to trough). A light wave bends to pass through a crack underneath a door, this represents interference.

Therefore, the correct option is option C.

Answer:

The particles move faster and are far apart

Explanation:

A substance may exist in three states of matter; solid, liquid and gas.

In the solid state, there is very strong intermolecular forces between the particles of the substance. They can only vibrate or rotate about their mean positions but can not translate.

In the liquid state, the particles of the substance have a greater degree of freedom than in the solid. The magnitude of intermolecular forces is lower than in solids, the molecules can move at low speeds.

In a gas, the molecules are separated from each other with negligible intermolecular interaction hence they move at very high speed.

Therefore, for the water gas particles in the air above the cup; the particles move faster and are far apart.

Answer:

See explanation

Explanation:

All gases are held together by weak dispersion forces. One would now ask; Since the electronegativity difference between carbon and oxygen is about 1.0 while the electronegativity difference between two oxygen atoms is 0.0, why are they both gases at room temperature?

The answer lies in the recognition of two facts;

1) The dipole moment is a vector quantity so we also consider its direction

2) possession of polar bonds does not necessarily make a polar molecule.

We all know that a polar molecule will have greater intermolecular forces between its molecules and will most likely be a liquid instead of a gas. However,if we look at the overall dipole moment in CO2, we will notice that the direction of the dipole moment due to the two C-O bonds are opposite to each other hence they cancel out each other leaving the CO2 molecule with a zero effective dipole moment just as oxygen gas.

Hence, possession of polar bonds does not necessarily make a polar molecule. Therefore both oxygen and CO2 are gases at room temperature.

3)6 electrons and neon

In an atom there are levels of energy in the shell and sub shell  

This energy level is expressed in the form of electron configurations.  

The electron configuration Oxygen (atomic number = 8) :

1s²2s²2p⁴

Oxygen will try to achieve stability (according to the octet rule) by binding 2 electrons so that the 2p orbits are filled with 6 electrons, so that the configuration is stable like the noble gases Neon

₁₀Ne = 1s² 2s² 2p⁶

Answer:

rainfall/water

Explanation:

The possession of drip tips by the leaves of plants in the rainforest is a form of adaptation against high rainfall. Without the drip tips on leaves, water will persist on the surface of leaves, and in conjunction with the warm climate, promotes the growth of pathogens such as fungi and bacteria.

Hence, the possession of drip tips on leaves is an indication of the prevalence of water in the rainforest region.
