Which of the following is an extensive property?

Identify the false statement regarding an isothermal process from the following.

If in a container neither mass nor heat exchange occurs,then it constitutes a

Identify the intensive quantity from the following.

At $T(K)$, $2 \ mol$ of an ideal gas is allowed to expand reversibly and isothermally from a pressure of $10 \ atm$ to $1 \ atm$. The work done (in $kJ$) is $(R=8.3 \ J \ K^{-1} \ mol^{-1})$.

Assertion : During an adiabatic process,heat energy is not exchanged between the system and its surroundings.
Reason : The temperature of a gas increases when it undergoes an adiabatic expansion.
