Answer : The volume of one mole of gas is dependent of temperature and pressure.
Explanation:
At 0oCand1atm one mole of an ideal gas would be ≈22.4L, which is the same as 22.4dm3
If you double the pressure, the same amount (mole) of gas would take up only half the space.
If the temperature changes (and pressure stays constant), the gas will expand or contract by about 1%/3o.
