One mole of oxygen is heated from 0°C, at constant pressure, till its volume increased by 10%. The specific heat of oxygen, under these conditions, is 0.22 cal/g-K. The amount of heat required is
Options:
Answer:
A
Solution:
At constant pressure V ∝ T, so Δ T = 0.10 × 273 = 27.3 K. Mass of 1 mol O2 = 32 g. q = 32 × 0.22 × 27.3 cal = 32 × 0.22 × 27.3 × 4.2 J. Matches (a).
