Question

A metal piece of mass 5 g has thermal capacity 2.5 JK⁻¹. If the mass of the metal is tripled, then its specific heat capacity will be ______.

पर्याय

• 7.5 JK⁻¹

• 2.5 JK⁻¹

• 1.5 Jg⁻¹K⁻¹

• 0.5 Jg⁻¹K⁻¹

Answer 1

A metal piece of mass 5 g has thermal capacity 2.5 JK⁻¹. If the mass of the metal is tripled, then its specific heat capacity will be 0.5 Jg⁻¹K⁻¹.

Explanation:

Thermal capacity = Mass X SHC

Using this relation, we get,

SHC = `2.5/5`

= 0.5 Jg⁻¹K⁻¹

SHC is independent of mass, so tripling the mass does not affect the SHC value for a substance.
