Explanation:
Quantity of heat required to raise 5 kg of water from 20 0C to 1000C is given by the formula:Q=m×c×ΔT(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.
=266.858kJDT
= temperature difference
=100-20
=80 0C.
