WebApr 5, 2024 · Latent heat is only a positive quantity. It cannot be negative. Only the latent heat of condensation and the fusion can be negative. Other than that, all others are positive. Comparison Table What is Sensible Heat? When we heat an object, the temperature in that object will get raised. This is what we call sensible heat. WebJun 7, 2024 · The transition from liquid to solid when the temperature is rising is equivalent to the enthalpy of fusion being negative. To explain this behaviour one must turn to quantum mechanics. It would seem that during that transition one goes from a less disordered liquid to a more disordered solid and that is in fact what is actually happening. incite sports

WebAs a result of the strong temperature dependence of saturation vapor pressure, latent cooling of the surface dominates sensible cooling from a wet surface at temperatures such as those in the tropics, but in high latitudes during winter sensible heat transport can be of greatest importance. WebThe latent heat of vaporization is the amount of heat needed to cause a phase change between liquid and gas. L f and L v are coefficients that vary from substance to substance, depending on the strength of intermolecular forces, and both have standard units of J/kg. See Table 11.3 for values of L f and L v of different substances.
