An ideal gas undergoes isothermal compression from 5 m 3 to 1 m 3 against a constant external pressure of 4 Nm –2 . Heat released in this process is used to increase the temperature of 1 mole of Al. If molar heat capacity of Al is 24 J mol –1 K –1 , the temperature of Al increases by:
A
K
B
K
C
1 K
D
2 K
Text Solution
Verified by ExpertsThe correct answer is:
B
W = –4 [1–5] = 16 J
16 = 1 × 24 × Δ T
Δ T = 
K
