Question

The ratio of thermal capacities of two spheres A and B, if their diameters are in the ratio 1 : 2, densities in the ratio 2 : 1, and the specific heat in the ratio of 1 : 3, will be –

• A. 1 : 6
• B. 1 : 12
• C. 1 : 3
• D. 1 : 4

Answer 1

Answer: (B)

1 : 12

Answer 2

$\frac{H_{1}}{H_{2}}$= $\frac{m_{1}s_{1}}{m_{2}s_{2}}$= $\frac{\rho_{1}V_{1}s_{1}}{\rho_{2}V_{2}s_{2}}$
