Why are temperature and specific volume independent properties?
Let all air out of a balloon (air volume expands); is the air hotter?
Temperature and volume are independent. But you might be confusing them with pressure. … The ideal-gas-law tells the relationship (for idealized gas):
$$pV=nRT$$
$p$ being pressure, $V$ volume, $n$ amount of sumbstance (number of molecules in moles), $R$ the gas constant and $T$ temperature …
