Question

How much heat energy in joules must be supplied to 14 grams of nitrogen at room temperature to raise its temperature by 40° at constant pressure. Molar mass of nitrogen = 28 and R is the gas constant

Moderate

A

50 R
B

60 R
C

70 R
D

80 R

Solution

$\begin{array}{l} dQ = {nC}_{p} dT = \frac{1}{2} \times \frac{7}{2} \times R \times 40 \\ dQ = 70 R \end{array}$
