AIPMT MAINS 2012 Chemistry Specific Heat MCQ Question

Type: MCQ-numerical-Medium-Class 11

Equal volumes of two monoatomic gases, A and B, at same temperature and pressure are mixed. The ratio of specific heats (CpCv)\left( \frac{C_p}{C_v} \right) of the mixture will be:

A

0.83

B

50

C

3

D

67

Correct Answer

Option D

Detailed Explanation

For a mixture of monoatomic gases, the ratio CpCv=53=1.67\frac{C_p}{C_v} = \frac{5}{3} = 1.67.
