Answer:
When we decrease temprature and increase pressure on a gas. It liquifies.
when we increase temprature and decrease pressure on liquid gas. It becomes gas again

Answer:
B. when volume and the number of particles are constant
Explanation:
According to Gay Lussac law,
For a given amount of gas at constant volume (V) and the number of particles are constant (n)
Pressure is directly proportional to the temperature of the gas.
It is given by the expression
[tex]P \propto T[/tex] ( at constant V and n)
[tex]\frac {P}{T} =k[/tex] (k is a constant )
When there is a change in the pressure or temperature
The expression is [tex]\frac {P_1}{T_1} =\frac {P_2}{T_2}[/tex]
Where
[tex]P_1[/tex] and [tex]P_2[/tex] are initial pressure and final pressure respectively
[tex]T_1[/tex] and [tex]T_2[/tex] are initial and final temperatures respectivley
Please Note:
Directly proportional means when one increases the other one too will increase that is when pressure increases temperature too will increases if volume and number of particles are constant.
