Answer 2

Answer:

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.
