Question
One mole of oxygen is heated from 0°C at constant pressure till its volume is increased by 10%. The specific heat of oxygen, under these conditions, is 0.22 cal/g-K. The amount of heat required is
Options
A.$32 \times 0.22 \times 27.3 \times 4.2\text{ J}$
B.$16 \times 0.22 \times 27.3 \times 4.2\text{ J}$
C.$\frac{32 \times 0.22 \times 27.3}{4.2}J$
D.$\frac{16 \times 0.22 \times 27.3}{4.2}J$
Solution
$q = n.C_{m}.\Delta T = 1 \times (0.22 \times 32) \times (273 \times 1.1 - 273) \times 4.2\text{ J}$
