Heat transferWhen 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
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. ...

evaporative cooling is highly effective. Heat is dissipated away from the body due to the high latent heat of vaporization of water. However, it's much harder to cool down in a sunny location than in a shady one because sensible heat from absorbed sunlight competes with the effect from ...
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
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...
Latent heat is energy either lost or gained by a substance when it changes state. Measured in energy, latent heat is caused by...
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...
A heat exchanger is a single device, such as a heater, a cooler, and a condenser. It is also part of a process equipment, such as the heat exchanger in ammonia. Because of the limitation of manufacturing process and scientific level of the early heat exchanger can only use simple structur...
is much more dense than the surrounding air then it will accelerate toward the surface. In the case of a heat burst, all the precipitation that cooled the air aloft has been vaporized. Therefore, the precipitation can no longer absorb latent heat. As this dense air accelerates toward the ...
