A metal piece of mass 5 g has thermal capacity 2.5 J K⁻¹. If the mass of the metal is tripled, then its specific heat capacity will be :
- (a)7.5 J K⁻¹
- (b)2.5 J K⁻¹
- (c)1.5 J g⁻¹ K⁻¹
- (d)0.5 J g⁻¹ K⁻¹

0.5 J g⁻¹ K⁻¹
Reason — As,
$\text {Specific heat capacity} = \frac {\text {Thermal capacity}}{\text {mass}} = \frac{2.5\ \text J \text K⁻¹}{5\ \text g} = 0.5\ \text J\ \text g⁻¹\ \text K⁻¹$
