Question

The temperature of 100. grams of water changes from 16.0ºC to 20.0ºC. What is the total number of Joules of heat energy absorbed by the water?

Answer 1

1.    Heat gained in a system can be calculated by multiplying the given mass to the specific heat capacity of the substance and the temperature difference. It is expressed as follows:

Heat = mC(T2-T1)
Heat = 100(4.184)(20 - 16)
Heat = 1673.6 J
