freezing, vaporization, or condensation. The energy is considered to be "latent" because it is essentially hidden within the molecules until the phase change occurs. It is "specific" because it is expressed in terms of energy per unit mass. The most common units of specific latent heat are...
What is latent heat? Latent heat, on the other hand, is the heat required to change the state of a substance without changing its temperature. All pure substances in nature can change their state; solids can become liquids (ice to water) and liquids can become gases (water to vapor). Th...
What is the dimensional formula of latent heat?HeatThere are two types of heat namely sensible heat and latent heat. The heat responsible for change in temperature of the body at constant phase is called sensible heat. The heat responsible for change in phase at constant temperature is called ...
5 (a) State what is meant by the specific latent heat of fusion (melting) of a substance..[2](b)Ice cubes of total mass 70g, and at 0 C, are put into a drink of lemonade of mass 300g.All the ice melts as 23500J of thermal energy transfers from the lemonade to the ice. The...

So what, exactly, is latent heat? I am given to understand that the energy is stored in the molecule in the form of changes to bond angles. With water, the bond angle between the hydrogen atoms changes by a degree or so during melting. Here, the bond angle is described as well as ...
(a) State what is meant by the specific latent heat of fusion (melting) of a substance. 相关知识点: 试题来源: 解析 (a) energy/heat needed to change state of substance/melt(from solid to liquid at constant temperature/ melting point) per kg/per unit mass ...
What causes the latent heat of solidification Every explanation that I read says: "When a crystal (solid state) forms from a liquid, heat is being produced." This seems rather weird, why would the production of something as ordered as ice crystals also produce heat as they are being assembl...
