Heat Capacity/Specific Heat: °K= °C + 273. C = m c (here, c is “specific heat”) Recall: heat is needed at a phase transition! Latent Heat of Fusion (solid-liquid) or Latent Heat of Vaporization (Evaporation). The latent heats at these transitions are “normally” independent of direct of …

Latent heat - heat which produces a change in state without any change in temperature. Sensible heat - heat which produces a change in temperature without any change in state. If a substance is heated at a constant rate from the solid through to the gaseous state, a graph of temperature versus time would look as shown in Figure 5.

Specific latent heat of fusion: Formula: Specific latent heat of vaporization. Symbol: Units: Specific Latent Heat. Kinetic theory views all matter as consisting of individual particles in continuous motion in an attempt to relate the macroscopic behaviors of the substance to the behavior of its microscopic particles.
