Question

Collisions of helium atoms with the walls of a closed container cause

a. condensation.
b. gas pressure.
c. a decrease in volume.
d. an overall loss of energy.

Raising the temperature of a gas will increase its pressure if the volume of the gas
a. and the number of particles are increased.
b. is increased, but the number of particles is constant.
c. and the number of particles are constant.
d. is constant, but the number of particles is reduced.

Answer 1

In less scientific words

For number 1 is GAS PRESSURE

And number 2 is TEMPERATURE

• I hope this works for you guys

Answer 2

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.
