Heat Capacity v.s Specific Heat Capacity
Note:
Example: A piece of hot coal of mass 50 g at a temperature of 200^{o}C is dropped into 150 g of water at a temperature of 25^{o}C. Calculate the final temperature reached. (The specific heat capacity of coal and water are 710 Jkg^{1}K^{1} and 4200 Jkg^{1}K^{1} respectively.) Let final temperature be θ. Recall that change in temperature in ⁰C is same as change in temperature in K. Therefore, you do not need to convert the unit for temperature change. This is discussed under Kelvin Scale.
