Heat Capacities — MCQ Practice

An ideal monoatomic gas is heated at constant pressure. If the heat supplied to the gas is $Q$, what is the change in internal energy of the gas?

Two moles of an ideal diatomic gas are heated from $300\,\text{K}$ to $350\,\text{K}$ at constant volume. Calculate the heat supplied to the gas. (Given $R = 8.314\,\text{J/(mol·K)}$)

Which of the following statements about heat capacities is INCORRECT?

If the ratio of specific heats ($\gamma$) for an ideal gas is $1.4$, what type of gas is it likely to be?

A $2\,\text{kg}$ block of copper (specific heat capacity $385\,\text{J/(kg·K)}$) is heated from $20^\circ\text{C}$ to $70^\circ\text{C}$. Calculate the heat absorbed by the copper block.

For a gas, if $C_P/C_V = 1.67$, what is the value of $C_V$ in terms of $R$?
