How much heat is lost when 71.07g of steam at 100 degrees condenses to form liquid water at 100 degrees

Q = 160.36[kJ], is the heat lost.

Explanation:

This is a thermodynamic problem where we can find the latent heat of vaporization, at a constant temperature of 100 [°C].

We know that for steam at 100[C], the enthalpy is

For liquid water at 100[C], the enthalpy is

Therefore

The amout of heat is given by:

thermal energy is the answer
