We have that The volume of real gas will change if “P” increases upto 500 atm and temperature decrease upto 0°C there will be
. Volume decreases by 0.05%
OPtion B
From the question we are told that
if “P” increases upto 500 atm
temperature decrease upto 0°C
Generally the equation for the ideal gas equation is mathematically given as
P=\frac{nRT}{V}
Where
n=1
R=0.08
Therefore
The volume is directly proportional to temperature
Therefore
. Volume decreases by 0.05%

Answer:
19.278049929737628457607385688801
Explanation:
Volume = L * W * H
Volume = 17.78 * 9.21 * 4.45 = 728.70441
Density = Mass / Volume
Mass = 14,048
14,048 / 728.70441 = 19.278049929737628457607385688801
Density = 19.278049929737628457607385688801
Explanation:
So density = mass/volume
Using this formula we'll solve the question.
mass = 14,048g/1000 = 14.048 kg
volume = 17.78/100 x 9.21/100 x 4.45/100
volume = 0.3143 m³
density = 14.048 kg/ 0.3143 m³
density = 44.69 kg/m³
round off to = 44.7 kg/m³

A pediatrician uses the model above to estimate the height h of a girl, in inches, in terms of the girl's age a, in years. Based on the model, what is the estimated height of a 2-year-old girl?
Answer:
h = 34.2 in
Explanation:
h = 3.0a + 28.2
h = height of a girl.
a = age of a girl.
h = 3.0a + 28.2
h = 3.0(2) + 28.2
h = 6 + 28.2
h = 34.2
The estimated height of a 2-year-old girl is 34.2 in.

In rutherfords gold foil experiment, most alphas particles passed through the gold foil without deflection and were detected on the screen. What caused the particles to pass through without any deflection?
Answer:
The vast majority of the volume in an atom consists of the electron orbitals with electrons that have too little mass to deflect the alpha particles. So most pass right through the foil. Only the ones hitting the nucleus are deflected.
Explanation:
The whole reason Rutherford and his students conducted this experiment was to test the then current hypothesis that an atom consists of a homogeneous blend of atomic particles, known as the "plum pudding" model. If so, there should be no, or minimal, deflection of particles. That's not what they found. Since particles were found to be deflected, the group concluded that atoms must contain a large object, which became known as the nucleus.
In your own words, summarize the contrasting arguments of Democritus and Aristotle about the composition (make up) of matter.
Answer:
Aristotle disagreed with Democritus and offered his own idea of the composition of matter. According to Aristotle, everything was composed of four elements: earth, air, fire, and water. The theory of Democritus explained things better, but Aristotle was more influential, so his ideas prevailed.

If an object at a distance of 6,400 km from the center of the earth weighs 10N, what will be its weight if it is lifted to 12,800 km from the center of the earth? ion:
Answer:
2.5N
Explanation:
since force is inversely proportional to square of the distance apart. that means the ratio of distance apart. so u have 12800×12800÷(6400××6400)=4/1
so the weight will be reduced to 1/4 of 10N
