i. The heat energy required to change substance from one state to another at constant temperature is called as latent heat of substance. ii. When latent heat is given off, the bonding between atoms or molecules of a substance strengthens, causing trans
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). These changes of state ...

(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 ...
Latent Heat of Vaporization: The latent heat of vaporization is the heat absorbed or released when matter vaporizes, changing phase from liquid to gas phase at a constant temperature. Sensible Heat: Although sensible heat is often called latent heat, it isn't a constant-temperature situation, nor...
What is thermal energy? Thermal energy refers to energy within a system that’s created by the random motion of molecules and atoms. As motion increases, more energy is produced. This energy is transferred in the form of heat. The flow of thermal energy from one system to another is the ...
