This problem can be solved using the First Law of Thermodynamics, which states that the change in internal energy (Delta U) of a system is equal to the heat added to the system (Delta Q) minus the work done by the system (W). The formula is: The increase in internal energy is 2072 J.
The latent heat of vaporization of water is 2,240 J. If the work done in the process of vaporization 1g is 168 J, then the increase in internal energy is?
