Heat energy gained or lost:
- Heat energy gained or lost by a body depends on its mass, nature, and change in its temperature.
- Mathematically, it can be represented by:
Q = m × c × ΔT
Q = Heat gain or loss, m = mass, c = specific heat, ΔT = Change in temperature
Heat capacity:
- Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to an object to produce a unit change in its temperature. Heat capacity= mass specific x heat capacity
- The SI unit of heat capacity is joule per kelvin (J/K).
Calculation:
Given:
Mass, m = 2.5 kg, ΔT = 10°C, Specific heat capacity, c = 500 Jkg-1K-1
Heat capacity = m × c = 2.5 × 500 = 1,250 JK-1
