calculations would be much appreciated thanks
here is a similar problem, change the numbers
What is the energy needed to heat 1 kg of ice at –20ºC to steam at 150ºC
Ans:
specific heat of water is 4.186 kJ/kgC
specific heat of ice is 2.06 kJ/kgC
specific heat of steam is 2.1 kJ/kgK
heat of fusion of ice is 334 kJ/kg
heat of vaporization of water is 2256 kJ/kg
5 parts to this problem, add them up to get the total
to warm ice to 0C
E1 = 2.06 kJ/kgC x 1 kg x 20C
to melt ice
E2 = 334 kJ/kg x 1 kg
to warm water from 0C to 100C
E3 = 4.186 kJ/kgC x 1 kg x 100C
to boil water
E4 = 2256 kJ/kg x 1 kg
to heat steam from 100C to 150C
E5 = 2.1 kJ/kgC x 1 kg x (150–100)C
E = E1 + E2 + E3 + E4 + E5
