How much heat is absorbed by 15.5 g of water when its temperature is increased from 20.0°c to 50.0°c? the specific heat of water is 4.184 j/(g°

Answer : The heat absorbed by the water is 19.4 kJ

Explanation :

Formula used :

or,

where,

Q = heat absorbed = ?

m = mass of water = 15.5 g

c = specific heat of water =

= initial temperature  =

= final temperature  =

Now put all the given value in the above formula, we get:

Therefore, the heat absorbed by the water is 19.4 kJ
