If two sphere having same radius but the ratio of their specific heat is 2 : 1 and the ratio of their density is 1 : 4 then the ratio of their heat capacity is –

A

2 : 1

B

1 : 2

C

1 : 1

D

1 : 4

Answer

1 : 2

Explanation

Solution

C1C2=ρ1v1s1ρ2v2s2\frac{C_{1}}{C_{2}} = \frac{\rho_{1}v_{1}s_{1}}{\rho_{2}v_{2}s_{2}}

= 21×14=12\frac{2}{1} \times \frac{1}{4} = \frac{1}{2}
