(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 ...
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...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
The unit of heat is joule (J) in SI unit system and calorie is used in BTU system of units. For heat transferred, watt is the standard unit.
What is latent heat of evaporation?Evaporation:Evaporation is the process where any substance in its liquid form is turned into its gaseous form. Evaporation is an endothermic process which means that the liquid should acquire enough energy to undergo this phase change....
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...
1,848 9 MadmanMurray said: I did a lab experiment were we measured the latent heat of fusion of ice but I am not quite sure what that is. I read that latent heat of fusion is the energy(heat) it takes to change liquid to solid. Is that true? Why would...

The dogs will be gradually exposed to the possible situations.
Natural Draft Cooling Tower Definition: A natural draft cooling tower is defined as a heat exchanger that cools water by direct contact with air, using convective flow for air circulation. Working Principle: It works by using sensible heat transfer and latent heat transfer to cool water and heat...
