Question

Calculate the heat capacity of a copper vessel of mass 150 g if the specific heat capacity of copper is 410 $JK{g}^{-1}{K}^{-1}$ . How much heat energy will be required to increase the temperature of the vessel from ${25}^{0}C$ to ${35}^{0}C$?

• A. 600 J
• B. 400 J
• C. 615 J
• D. 415 J

Answer 1

The correct option is C

615 J

Mass = 150 gm

Specific heat capacity = 410 $JK{g}^{-1}{K}^{-1}$​

Temperature, $\Delta T={35}^{0}C-{25}^{0}C={10}^{0}C$

Heat Capacity = mass $\times$ specific heat capacity = $\frac{150\times 410}{1000}$ $JK{g}^{-1}{K}^{-1}$​​ = 61.5 J

Heat Energy, $\Delta \theta$ = Heat capacity, $c^{\prime }\times \Delta T=61.5\times 10=615J$
