Energy mass and specific latent heat
WebJan 17, 2024 · figure 1: A method for measuring the latent heat of vaporization. The amount of thermal energy provided to water at its boiling point is calculated using electrical energy = I t V. The mass vaporised needs to be recorded. The specific latent heat L= I t … WebOn the other hand, the latent heat was dominant after 13.00 o’clock. Due to the fins, the seawater in Cases B and C was at a higher temperature than that in Case A, and then a high rate of evaporation occurred in Cases B and C. Increasing the fin number raised the latent heat; consequently, the useful heat for Case C was higher.
