Embibe Experts Solutions for Exercise 2: Assignment

Among the following, which is not a state function?

If an ideal gas expands isothermally from $50 \mathrm{L}$ to $100 \mathrm{L}$ against $2 \mathrm{atm}$ external pressure, then values of $\mathrm{W},\mathrm{\Delta U}$ and $\mathrm{Q}$ respectively will be

If $1 \mathrm{mol}$ of an ideal gas at constant temperature changes its pressure from$5 \mathrm{atm}$ to $2 \mathrm{atm}$ and volume from $4 \mathrm{L}$ to $10 \mathrm{L}$, then enthalpy change will be

If equal moles of following gases are taken at constant temperature and pressure then gas of highest entropy is

Correct expression of enthalpy of combustion is

Select the pair of intensive properties

If calorific fuel value of ${\mathrm{C}}_2{\mathrm{H}}_6$ is $\mathrm{xkJ}/\mathrm{g}$ then the heat of combustion of ${\mathrm{C}}_2{\mathrm{H}}_6$ (in $\mathrm{kJ}/\mathrm{mol}$ )is

Work done is always zero for
