Calculate the kilocalories needed to heat 4.5 kg of water from 22 Celsius to 23 Celsius
Expert Answer
Energy is required to raise the temperature of water from 22 degree C to 23 degree C.
Given,
mass of water = 4.5 kg = 4500 g
[1 kg = 1000 g]
specific heat of water = 1 cal/g. degree C
change in temperature = 23 - 22 = 1 degree C
Using,
heat required = mass x specific heat x change in temperature
