Question

A solid of mass 1.2 kg has a specific heat capacity of 1.4 Jg⁻¹°C. The heat capacity of the solid in SI system is:

विकल्प

• 1680 JK⁻¹

• 1675 JK⁻¹

• 1685 JK⁻¹

• 1670 JK⁻¹

Answer 1

1680 JK⁻¹

Explanation:

Convert the mass to grams:

1.2 kg = 1200 g

Heat capacity (C') = mc

= 1200 × 1.4

= 1680 J°C⁻¹

Equivalent to 1680 JK⁻¹
