Question

One mole of an ideal diatomic gas (Cv = 5 cal) was transformed from initial 25°C and 1 L to the state when temperature is 100°C and volume 10 L. The entropy change of the process can be expressed as (R = 2 calories/mol/K) (a) 3 n 2 n10 373 (b) 5 n 2 n10 298 (c) 7 n 2 n (d) 5 n 2 n

Accepted Answer

B

One mole of an ideal diatomic gas (Cv = 5 cal) was transformed from initial 25°C and 1 L to the state when temperature is 100°C and volume 10 L. The entropy change of the process can be expressed as (R = 2 calories/mol/K) (a) 3 n 2 n10 373 (b) 5 n 2 n10 298 (c) 7 n 2 n (d) 5 n 2 n
