Question

The ratio of radii of two solid spheres made of same material is 3 isto 1.the ratio of their heat capacity is?

Answer 1

The ratio of their thermal capacity is 27:1

Explanation:

thermal capacity = Mass X specific

Due to same material both spheres will have same specific heat. also

mass = volume (V) density(r)\ratio of thermal capacity

      ρ$\frac{m_{1} }{m_{2} } = (\frac{r_{1} }{r_{2} } ){3} =(\frac{3}{1} )^{3} = 27:1$
