Question

The specific heat capacity of water in SI system is:

विकल्प

• 4.2 J kg⁻¹ K⁻¹

• 42 J kg⁻¹ K⁻¹

• 4200 J kg⁻¹ K⁻¹

• 420 J kg⁻¹ K⁻¹

Answer 1

4200 J kg⁻¹ K⁻¹

Explanation:

The SI system measures heat in Joules, mass in kilograms, and temperature in Kelvin. This value means it takes exactly 4200 Joules of heat energy to raise the temperature of 1 kg of water by 1 K.
