If 75 g of liquid water (c=4.18 j/g- degree c) in a calorimeter changes temperature from 25 degree c to 75 degree c how much heat was transferred

Answer :  15675 J of heat was transferred.

Solution : Given,

Mass of liquid water = 75 g

Specific heat capacity =

Initial temperature =

Final temperature =

Formula used :

where,

q = heat energy

m = mass

c = specific heat capacity

= change in temperature

= initial temperature

= final temperature

Now put all the given values in the above formula, we get

Therefore, 15675 J of heat was transferred.
