Katz · Answer 1

1) Option b: gas pressure.

This is sustainted by the kinetic molecular theory of the gases.

2) Option c: raising the temperature of the gas will increase the pressure if the volumen of the gas and the number of particles are constant.

PV = nRT

If V and n are constant, P is proportional to T, then if T increase P will increase too.
