How many kilocalories are required to heat 100.00 g of water from 34.2°c to 96.5°c?

Heat required in calories is given by product of mass in g and change in temperature in degree Celsius.

Formula is given by:

where, Q = heat required in calories

m = mass of substance in g

= change in temperature in degree Celsius

Insert the given vales of mass of water and temperature in above formula, we get:

 =

=

Now,

=

Thus, heat in kilocalories  =

the answer is c i believe
