Acompound differs from a mixture in that a compound
-contains only one element
- varies in chemical composition depending on the sample size
- has a definite composition by the elements that the compound contains
- can be classified as either heterogeneous or homogeneous

A compound differs from a mixture in that a compound has a definite composition by the elements that the compound contains.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
