How does heat energy affect evaporation?
Heat energy causes evaporation. It evaproates water, or you could say it turns liquid into gas.
Define latent heat of fusion and latent heat of vapourisation?
Latent heat of vapourisation can be define as the rate by which water is heat to vapourise, it has a difference with evaporation because evaporation occurs directly when the water start heatin while vapourisation always start in a specific temperature
Is evaporation a method of heat transfer?
Yes
Why does evaporation need the sun in order for it to occur?
It doesn't, evaporation requires heat. It just so happens that the Sun often provides the heat required.
Contrast what happens to thermal energy in evaporation and condensation?
In evaporation, the heat is transferred to the substance being evaporated from some heat source or the surroundings. It is released by the substance.
What makes evaporation happen faster?
When there is more heat.
What factors can make evaporation happen faster when your clothes are hung out to dry?
heat and air
What is the relationship between the hydrologic cycle and thermal energy?
Well, without the sun, witch is heat, the is no evaporation. Without evaporation there is no hydrologic cycle.
What two processes need heat to happen?
Evaporation and sublimation (there are lots of other processes, too)
What will happen if you heat the sugar without water?
Nothing will happen :))
What part does heat play in evaporation?
heat plays a big part in evaporation by making it occur. we need heat for evaporation so water can evaporate
What have scientist already discovered about heat and evaporation?
that the more heat u have the quicker the evaporation
What factors would make evaporation happen faster?
Heat and air movement (wind)... also lack of moisture in the air.
Which process in the water cycle would happen more efficiently if more heat energy and light energy increased?
evaporation
What is latent heat evaporation?
Latent heat of evaporation of water to steam is 2270 KJ/Kg
What part does evaporation play in?
heat plays a big part in evaporation by making it occur. we need heat for evaporation so water can evaporate
What is heat transfer in condensation?
It's complicated and hard to explain, but I'll try my best. Evaporation occurs when a liquid changes to a gas, but only on the surface of the liquid volume. The gas molecules transfer heat to the liquid molecules. An unequal distribution of heat causes some liquid molecules to become gas molecules. It is random and uneven. Energy from the sun also spawns evaporation. When evaporation does happen, the molecules that leave the liquid body takes a lot of heat with it, therefor the average temperature of the liquid decreases. Evaporation depends on heat, humidity, and air movement.
