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 ...
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...
When heat is provided to a material, it increases the rms velocity of the particles in the material, thereby increasing the temperature of the material.Answer and Explanation: When heat is provided to a material, generally the temperature of material increases. However, sometimes the temperature ...
Step-by-Step Solution:1. Understanding Specific Latent Heat: - The specific latent heat of melting is the amount of heat required to convert a unit mass of a solid into a liquid without a change in temperatu
Learn about sweat. Read about the meaning of sweat and what sweat is in the body. Understand what sweat is made of and discover if urine and sweat are the same things. Related to this Question What is shivering? What is a head cold?
(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 ...
"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 assembled? I understand that there is an explanation in thermodynamics that goes as follo...
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 ...
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...
