Question

in convection heat is transfered from paticle to particle ,by evaporation and condensation , by direct contact with heat source ,by actual movement of particles

Answer 1

hey mate >>

Evaporation occurs when an influx of heat causes a liquid to change state to a gas.

Evaporation is a cooling process because the heat required to change it to a gas is drawn away from the surroundings, leaving the surroundings cooler (particles speed up and take heat from the liquid when evaporating)
