Which of the following is not true?

The enthalpies of the elements in their standard states are assumed to be

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.

Which among the following are intensive and extensive properties respectively?

The law of $Lavoisier$ and $Laplace$ illustrates:

$1 \ mol$ of an ideal gas is allowed to expand isothermally and reversibly from $1 \ L$ to $5 \ L$ at $300 \ K$. The change in enthalpy (in $kJ$) is $(R = 8.3 \ J \ K^{-1} \ mol^{-1})$.
