The amount of heat measured for a reaction in a bomb calorimeter is

Calculate the work done in joule if $1 \ mole$ of ideal gas is compressed from $25 \ dm^3$ to $13 \ dm^3$ at constant external pressure $4 \ bar$. (in $J$)

An ideal gas expands in volume from $1 \times 10^{-3} \ m^3$ to $1 \times 10^{-2} \ m^3$ at $300 \ K$ against a constant pressure of $1 \times 10^5 \ N \ m^{-2}$. The work done is

Which of the following is $NOT$ an intensive property?

Which of the following is an isolated system?

What is the internal energy change when $2$ moles of an ideal gas at $25^{\circ} C$ is compressed isothermally and reversibly from $1.0 \ bar$ to $10.0 \ bar$?
