A. Specific heat
B. Thermal capacity
C. Water equivalent
D. None of the above
Correct Answer:
Option B – Thermal capacity
Explanation
Heat capacity or thermal capacity: The amount of heat to be supplied to an object to produce a unit change in its temperature(1k).

![An immersion heater rated 400W, 220V is used to heat a liquid of mass 0.5kg. If the temperature of the liquid increases uniformly at the rate of 2.5ºC per second, calculate the specific heat capacity of the liquid.
