In each of these examples energy is transferred by one of the following four types of energy transfer: mechanical work - a force moving an object through a distance electrical work - charges ...

The particles of liquids are further apart than solids. This means that most liquids are poor conductors of heat because the frequency of collisions is reduced. The particles of gases are even ...

The efficient conversion of solar energy into storable forms of chemical energy is the dream of many engineers. Nature found ...

Photosynthesis -- mainly carried out by plants -- is based on a remarkably efficient energy conversion process. To generate chemical energy, sunlight must first be captured and transported further.
