Moisture needs to take in energy to evaporate. That's why your skin feels cooled when it happens to sweat on your skin.
Ice packs absorb heat energy from their surroundings, causing them to cool down. When placed on the body, the ice pack absorbs heat, which lowers the temperature of the area it is in contact with.
The only process which requires the input of energy is evaporation.
All objects give off thermal energy, also known as heat, in the form of infrared radiation. Thermal energy is a result of the motion of the atoms and molecules that make up the object.
A bonfire gives off light energy in the form of flames and heat energy in the form of warmth.
On average, humans give off about 100 watts of heat energy.
Plants take in carbon dioxide and give off oxygen. I think the question is about planets. Planets take in energy from the Sun (mainly in the visible part of the spectrum). Planets then give off infra red radiation.
I think when they receive carbon dioxide
The human body gives off heat in four ways (just like energy): By touch (conduction) by emission (radiation) by circulation (convection) and by sweat (evaporation)

Infrared light doesn't "give off" energy; in this case, it IS the energy.
you give off calary and diet energy
yea it does
Computers give off mostly heat, but also give off magnetism in the form of radio waves. Plus their displays give off light energy and the speakers give off sound waves. The fans inside create kinetic energy.
Yes, we take in energy in the form of food that we digest and use for our cells and we give off heat (and sound energy when we talk).
Yes, this is the perspiration.
Fuels give off energy when burned, typically in the form of heat and light. This energy is released by chemical reactions that take place when the fuel combines with oxygen in a process known as combustion.
Ice packs absorb heat energy from their surroundings, causing them to cool down. When placed on the body, the ice pack absorbs heat, which lowers the temperature of the area it is in contact with.
