1 mole of sulphur dioxide occupies a volume of 350 ml at 27^(@)C and 5xx10^(6) Pa pressure. Calculate the compressibility factor of the gas. Is it less or more compressible than an ideal gas ?

A person measure the presssures of his car tyre to be 2 times 10^5 Pa At that time the temperature and pressure of the atmosphere are 27^@C and 1 times 10^5 Pa respectively. Then he travels to another city where the temperature and pressure of the atmosphere are 12^@C and 6.7 times 10^4 Pa respectively. Them what will be the pressure of his car tyre at that time. Assume the volume of the tyre is same in both cases.
