If the pressure and the volume of certain quantity of ideal gas are halved, then its temperature

If both the temperature and the volume of an ideal gas are doubled, the pressure

If both the temperature and the volume of an ideal gas are doubled, the pressure

At a given temperature and pressure, the volume of 1 mol of an ideal gas is 10 L. at the same temperature and pressure, the volume of 1 mol of a real gas is VL. At this temperature and pressure, if the compressibility factor of the real gas is greater than 1, then -

At constant pressure, the ratio of increase in volume of an ideal gas per degree rise in Kelvin temperature to its original volume is

At constant pressure, the ratio of increases in volume of an ideal gas per degree rise in kelbin temperature to its volume is
