Question:

Different materials heat up in different rates. This phenomena is important and could be seen everywhere in our daily life: When we are heating different foods on the stove, when we go to the beach and feel the hot sand compared to the cool water, and many more. The term "specific heat capacity” is the amount of energy (heat) required to change the temperature of one mass unit of a substance by one degree celsius. Specific heat capacity, therefore,  has units of energy per mass per degree. Each material has a different specific heat capacity. Please look at the video below and answer the following question.




Specific heat capacity of water is 4.2 KJ/(Kg 0c) and specific heat capacity of milk is 3.8 KJ/(Kg 0c).  According to the video that you saw, if you will heat 100gr of water and 200gr of milk at same initial temperature, for the same time and on the same stove, which fluid will be hotter at the end of heating?
