Question:medium
Find the heat energy that must be supplied to 14 g of nitrogen at room temperature to raise its temperature by \(48^\circ\text{C}\) at constant pressure. (Molecular weight of nitrogen = 28; \(R\) is the gas constant; \(C_p = \frac{7}{2}R\) for a diatomic gas.)
Find the heat energy that must be supplied to 14 g of nitrogen at room temperature to raise its temperature by \(48^\circ\text{C}\) at constant pressure. (Molecular weight of nitrogen = 28; \(R\) is the gas constant; \(C_p = \frac{7}{2}R\) for a diatomic gas.)
Show Hint
Always identify if the gas is monoatomic or diatomic to verify \(C_p\). Nitrogen (\(N_2\)) is diatomic. Also, remember that for calculating heat energy, the change in temperature in Celsius is identical to the change in Kelvin.
