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 :
0.5 J g⁻¹ K⁻¹
Reason — As,
Specific heat capacity=Thermal capacitymass=2.5 JK−15 g=0.5 J g−1 K−1\text {Specific heat capacity} = \dfrac {\text {Thermal capacity}}{\text {mass}} = \dfrac{2.5\ \text J \text K⁻¹}{5\ \text g} = 0.5\ \text J\ \text g⁻¹\ \text K⁻¹Specific heat capacity=massThermal capacity=5 g2.5 JK−1=0.5 J g−1 K−1
