Question

how much heat energy is necessary to raise the temperature of 10kg of water from 40°C to 100°C​

Answer 1

Answer:

,

Explanation:

here is ur answer.......

Answer 2

Explanation:

given: m=10kg,c=1kcal/kg and change in temperature ∆T=100-40=60°c

Energy to be supplied to water=energy gained by water

=mass of water × specific heat of water × change in temperature of water

= m×c×∆T

= 10×60°c

= 600 kcal

Hence, the heat energy necessary to raise the temperature of water=600kcal
