ten calories ...

Question

ten calories of heat are added to two grams of liquid water.The temperature of the water (specific heat capacity of water is 1caloriegm degree C)

Open in App

Solution

Using the relation,
Energy = mass x specific heat x Change in temperature
10 cal = 2g x 1cal/g-ºC x dT
Change in temperature=10/2=5
Hence the temperature of water rises by 5 degree Celsius.
