Standard Books Physics Specific Heat MCQ Question with Solution

Two moles of oxygen is mixed with eight moles of helium. The effective specific heat of the mixture at constant volume is

A

1.3 R

B

1.4 R

C

1.7 R

D

1.9 R

Correct Answer

Option C

Detailed Explanation

The molar specific heat of the mixture at constant volume is calculated using the formula: $(C_v)_{\text{mixture}} = \frac{n_1 C_{v_1} + n_2 C_{v_2}}{n_1 + n_2}$ . Substituting the values, we get $1.7 R$ .
