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 ...
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...
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...
What is a quantitative study? What is an observational study? What is the unit of heat energy? How do you define specific heat? What is heat of fusion? What is heat of compression? What is the specific heat of water? What is the unit of latent heat?
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...
In physics, what is latent heat? How can you cause heat to flow from a body at a lower temperature to one at higher temperature? How much heat is required to raise the temperature of 70 g of water from 20 degrees Celsius to 80 degrees C?
