Specific Heat Capacity — Prelims Questions

An ideal gas has a molar specific heat at constant volume $C_v = 3R/2$. What is the ratio of specific heats ($gamma$) for this gas?

A gas expands from volume $V_1$ to $V_2$ at constant pressure $P$. The heat supplied to the gas is $Q$. If the specific heat capacity at constant volume is $C_v$, what is the change in internal energy of the gas?

The molar specific heat of an ideal diatomic gas at constant pressure is $C_p$. If the gas undergoes an adiabatic process, what is the value of $C_p$ at moderate temperatures?

If $200,\text{J}$ of heat is added to $0.5,\text{kg}$ of a substance, and its temperature increases by $4,\text{K}$, what is the specific heat capacity of the substance?

Which of the following statements is TRUE regarding the specific heat capacities of an ideal gas?

A certain amount of heat is supplied to a monoatomic ideal gas, and its temperature increases by $20,\text{K}$. If the same amount of heat is supplied to a diatomic ideal gas (at moderate temperature) of the same number of moles, what will be its temperature increase?
