If the internal energy of an ideal gas U and volume V are doubled, then the pressure of the gas :

Do the internal energy of ideal gas depend upon volume?

Is the internal energy of an ideal gas a function of its pressure?

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

If pressure and temperature of an ideal gas are doubled and volume is halved, the number of molecules of the gas

If pressure and temperature of an ideal gas are doubled and volume is halved, the number of molecules of the gas

Internal energy and pressure of a gas of unit volume are related as:
