One mole of oxygen is heated from 0°C, at constant pressure, till its volume increased by 20%. The specific heat of oxygen, under these conditions, is 0.22 cal/g-K. The amount of heat required is
Options:
Answer:
D
Solution:
At constant pressure V ∝ T, so Δ T = 0.20 × 273 = 54.6 K. q = 32 × 0.22 × 54.6 cal = 32 × 0.22 × 54.6 × 4.2 J. Matches (d).
