While latent heat of fusion and vaporization are used in physics and chemistry, meteorologists also consider sensible heat. When latent heat is absorbed or released, it produces instability in the atmosphere, potentially producing severe weather. The change in latent heat alters the temperature of obj...

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...
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.[2] 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 ...
I (Martin Geddes) am experimenting with Substack’s “sections” feature to public content generated by AI that, while not “originally” my own, is the result of many hours of my training the AI and asking it interesting questions, selecting only the answers that may be helpful to my read...
Heat is a form of energy. Particles of matter ( atoms, molecules, etc. ) possess potential energy and kinetic energy. Total energy ( potential energy + kinetic energy ) of all particles particles of matter in a given sample is called its thermal energy
