How much more is the internal energy of 1 kg of water vapor at 100 degrees than 1 kg of water at 100 degrees?
| July 14, 2021 | education
The internal energy of 1 kg of water vapor at 100 ° С is more than the internal energy of 1 kg of water heated to 100 ° С by the amount of heat Q that must be supplied to turn water into steam:
Q = Lm, where L is the specific heat of vaporization of water, m is the mass of water.
Q = 2.3 * 10 ^ 6 J / kg * 1 kg = 2.3 * 10 ^ 6 J.
Answer: 2.3 * 10 ^ 6 J.
