Answer:
Pressure of the gas increases.
Step-by-step explanation:
If a gas is moved from a large container to a small one while its temperature and number of moles are kept constant, then the pressure of the gas would increase.
We can use the ideal gas equation to prove this.
PV = NRT
According to this equation, when the volume of the gas is decreased while the temperature and the number of moles are constant, then the pressure of the gas increases.
