$($T$)($F$)$ Temperature, density, specific internal energy: all are extensive properties.

$($T$)($F$)$ Refrigerant R$-134$a at critical conditions exists as an ideal gas.

$($T$)($F$)$ The heat capacity at constant pressure is much greater than the heat capacity at

constant volume for liquid system.

$($T$)($F$)$ The change in internal energy $(U)$ is always zero if the process involves an ideal

gas and undergoes an isothermal expansion or compression.

$($T$)($F$)$ Zeroth law of thermodynamics is applied whenever temperature measurement is

needed.
