Suppose a piston automatically adjusts to maintain a gas at a constant pressure of 5.80 atm . For the initial conditions, consid
er 0.04 mol of helium at a temperature of 240.00 K . This gas occupies a volume of 0.14 L under those conditions. What volume will the gas occupy if the number of moles is increased to 0.07 mol (n2) from the initial conditions?

Explanation:
When water is frozen then it is known as ice and its state is solid. So, its molecules will be held closer to each other as they are held by strong intermolecular forces of attraction.
As a result, its temperature will be minimum as its molecules have least kinetic energy.
It is known that kinetic energy of a substance is directly proportional to temperature.
As, K.E =
where K.E = kinetic energy
T = temperature
k = boltzmann constant
When solid changes into liquid state then it means molecules of a substance has gained kinetic energy due to which there occurs more collisions between the molecules.
Hence, temperature of substance also increases.
Whereas when liquid state of a substance changes intro vapor state then it means that more kinetic energy has gained by the molecules due to which there will be much more collisions between the molecules.
Hence, temperature will be maximum in vapor state.
