Conduction. Heat travels from high to low to balance itself, in a cold pool our warm bodies will lose heat to balance the waters temperature.
Example: TV. Electricity- Heat, light, sound. Useful energy transfers would be electricity- light, sound because that's what your TV actually needs, but electricity- heat would be wasted energy or a non-useful energy transfer because your TV does not need to produce heat, unless of course you can't afford central heating, but then isn't heating more important than a TV???? Summary: Useful energy transfer: The purpose of the object is fufilled by this transfer. Non-useful energy transfer: The purpose of the object is not fufilled by this transfer, and in effect, this transfer is a "side effect" of the useful energy transfer. These transfers waste energy.
Yes definitely. That too the medium has to be a material medium. Because sound is nothing but the longitudinal vibrations produced in the material medium. Hence the transfer of sound energy is nothing but the transfer of this vibrational energy through the material medium.
Different types of refrigerators achieve this in different ways. From an energy point of view, heat has the natural tendency to flow from hotter object to colder objects; making heat energy move the other way requires an energy input.
energy transfer allows things to heat each other and to allow motion because if particles did not interact with each other (energy transfer) each atom would be able to pass through other atoms
Conduction.... Why you ask because Conduction is the transfer of energy from one object to another object through direct contact.
Convection because convection is the transfer of energy through circulation(liquid or gas).
The ribosome is responsible for making proteins....these proteins are needed for energy... Similarly the mitochondria is responsible for making energy.. Get the picture?
Mitochondrion
The swimming pool contractor generally performs this function. However, the law holds the homeowner responsible for making sure it is done.

Mitochondria
Conduction. Heat travels from high to low to balance itself, in a cold pool our warm bodies will lose heat to balance the waters temperature.
Mitochondria are responsible for breaking down nutrients. They also take in nutrients and are responsible for making energy for cells.
they use sunlight and others to transfer it into energy.
