Question
Which of the following statements is incorrect for an ideal gas?
For two gases at the same temperature and volume, the gas with the higher pressure has the greater quantity of gas.
For two gases at the same pressure and volume, the one at the higher temperature is comprised of a larger quantity of gas.
At constant pressure and gas quantity, the volume is a linear function of the temperature as measured on the Centigrade scale.
It is possible for two gases at the same pressure and volume to have different temperatures.
According to the ideal gas law, the pressure of a gas can be zero only at a temperature of absolute zero.
Explanation / Answer
According to ideal gas equation PV=nRT
Statement-2 is in correct.
As for gas 1 P1V1=n1RT1
For gas 2 P2V2=n2RT2
If pressure and volume are equals then n1T1 = n2T2
Hence for higher temperature quantity of gas is lesser.
Rest of the statements are okay.
