For an ideal gas,the heat of reaction at constant pressure and constant volume are related as:

Which of the following is an intensive property?

In the equation $C_P - C_V = R$,what does $R$ represent?

Identify the process that proceeds with no heat exchange between the system and the surrounding.

Which of the following statements is not correct?

If $5 \ mol$ of an ideal gas expands from $10 \ L$ to a volume of $100 \ L$ at $300 \ K$ under isothermal and reversible conditions,then the work done,$w$,is $-x \ J$. The value of $x$ is $ . . . . . . $. (Given $R = 8.314 \ J \ K^{-1} \ mol^{-1}$)
