Question

explain why the precision of the latent heat experiment is improved by using hot water instead of room temperature water?

Answer 1

The precision of the latent heat experiment is improved by using hot water instead of room temperature water because latent heat is the energy required to change a phase. Room temperature is sort of in the medium of temperature. Boiling water has the closer temperature to a phase change. We know that when water starts to boil, it is changing to gas. Therefore, using liquid at the temperature closest to a certain phase will yield more accurate results.
