Heat in a body is attained when there is rapid movement in the molecules of a body or when there is kinetic energy in the body.
Melting is a process that requires heat to change a solid substance into a liquid, so it is a heat gain process. Heat is absorbed to break the bonds between the molecules in the solid and allow them to move more freely as a liquid.
When an object is hot, the temperature rises as heat is added. This increase in heat is called sensible heat. Solids can become liquids and liquids can become gases but changes like this require the addition or removal of heat. The heat that causes these changes is called latent heat.
When heat is added, it is called heat absorption or heat gain. When heat is subtracted, it is called heat release or heat loss.
The term used to describe when heat gain is equal to heat loss is thermal equilibrium. This means that there is no net change in temperature because the heat gained by a system is equal to the heat lost by the system.
Things that give off heat are called heat sources or heaters.
yes
There are a great many things that gain and lose heat. Metals for example gain and lose heat much more quickly than gasses.
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
Sure, if one object loses heat, another will gain it.However, it might then be called heat gain.
heat loss
A temperature change requires as gain or loss of heat energy.
NO Heat Loss , No Heat gain

Heat energy - yes. Temperature - no.

the material can gain or lose heat easily
