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?

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

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
