For what?
It requires a heat gain for the water,
but a heat loss for whatever the water is in contact with.
Lose
(Steam burns as it condenses on your skin and loses its thermal energy to you)
For what?
It requires a heat gain for the water,
but a heat loss for whatever the water is in contact with.
It loses energy.
Evaporation absorb heat.
Given out
it is heat gain!
Transpiration
The water evaporates into the air. This is called evaporation. Evaporation is caused by the heat of the sun. If it is cloudy or cold, the water is not likely to evaporate.
Latent Heat of Evaporation, or Evaporation Enthalpy. It is given in units of energy over unit of mass, i.e., KJ/Kg.
Newspaper and styrafoam.
Installing fiberglass batting will completely eliminate heat loss.
heat loss
evaporation
A temperature change requires as gain or loss of heat energy.
Heat gain, otherwise, a heat loss would be like turning off the heat beneath a saucepan on the stove.
Evaporation
NO Heat Loss , No Heat gain
Evaporation because it requires 2,260 Joules to gain heat energy. Condensation, freezing, and melting require less Joules than evaporation.
These are exact opposities - heat gain is an increase in energy that results in an increased temperature of the material. Heat loss is a loss in energy that results in a decreased temperature of the material.
