Q.
One mole of an ideal gas requires 207 J heat to raise the temperature by 1K, when heated at constant pressure. If the same gas is heated at constant volume to raise the temperature by the same range, the heat required will be (Take $R = 8.3\ Jmol^{- 1}\ K^{- 1}$)
A) 215.3 J
B) 198.7 J
C) 207 J
D) None of these
Explanation
(b) $C_{v} - C_{p} - R = 207 - 8.3 = 198.7$ J
