STANDARD 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 $1.7 R$ .
