At constant pressure, will a gas increase its volume with an increase in temperature?

According to General gas laws and kinetic molecular theory, 1) increase in pressure will result in a decrease in volume
2) answer to 2nd question is also affirmative.

Yes. Using the equation PV=nRT (P=pressure, V=volume,n=number of moles, R=gas constant, T=temperature) if the temperature is constant, increasing the pressure will decrease the volume. And, at constant pressure, increasing the volume will increase the temp.

The answer is YES. Using the ideal gas law, PV=nRT.
Example
P=1atm, n=2moles, R=0.08205L*atm/K*mol and T=275k the volume would be 45.13L (V=nRT/P).
If you increase the pressure to 2atm then V=22.56L.
If the pressure is constant at 1atm but the temperature changes from 275K to 300K then V=49.23L
Hopes this helps

use the ideal gas equation, pV=nRT press. x vol. =amt. x gas const. x temp. when p increases(T is constant,n,R is constant,) V will have to decrease when T increases(p,n,R is constant), V will have to increase too look at the above equation

Yes in both cases if the number of moles/molecules remains constant.
