A container of nitrogen gas $\left(N_{2}\right)$ at $23^{\circ} \mathrm{C}$ contains $425 \mathrm{L}$ at a pressure of 3.5 atm. If $26.6 \mathrm{kJ}$ of heat are added to the container, what will be the new temperature of the gas?

Key Concepts

Ideal Gas Law

This concept relates pressure, volume, temperature, and the amount of gas using the equation PV = nRT. It provides the framework to connect the macroscopic properties of a gas and is fundamental when determining the state of the gas before and after a process.

Internal Energy Change

For a process at constant volume, any added heat increases the internal energy of the gas. This internal energy change is directly related to the temperature change of the gas, following the relationship ?U = nC_V?T.

Molar Heat Capacity at Constant Volume

This concept involves the amount of heat energy required to raise the temperature of one mole of a substance by one degree Kelvin at constant volume. For diatomic gases like nitrogen, the molar heat capacity C_V is typically taken as (5/2)R, which reflects the degrees of freedom associated with molecular rotation in addition to translation.

Conversion of Energy to Temperature Change

This involves applying the relationship between the added heat and the temperature change using the current amount of substance (in moles) and its molar heat capacity, allowing one to calculate the new temperature after a specific amount of energy is added.
