Answer 2

Explanation:

Quantity of heat required to raise 5 kg of water from 20°c to 100°c is given by the formula:Q=m×c×∆T(Q is usually used to symbolize that heat required in a case like this.)For water,the value of .c is 4.186Jg°C.so,Q=750×4.186×85=266858J=266.858 KJDT=temperature difference=100-20=80 OC.
