YES, you cant create or destroy energy. all it does is transfer (gain or loss)
No it is not. Power is the rate at which work is done. Energy is another name for the total amount of work done. It may be thought of as power multiplied by time.
electrical power
(physics) the rate of doing work; measured in watts (= joules/second) - See more at: http://www.chacha.com/question/what-is-the-rate-of-doing-work-or-using-energy-(58%26%2345%3B19)#sthash.l6xRuIk4.dpuf
Power.
The term that represents the rate at which work is done is the watt. It is defined as 1 joule per second.
Yes ^that's not true. Actually work is not the rate at which you expend energy.
as we heat water,its temperature rises and the molecules start acquiring energy and collide with each other at an increasing rate..this makes water to expand..

"Power" is the rate of work, or of energy transfer.
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
Power is the rate of doing work or delivering energy whereas energy is the capacity for doing work.

electrical power
Power is defined as the rate at which energy is used, generated, moved, or converted.Power is the rate of speed at which work is accomplished.
Power is the rate at which work is performed or energy is converted. It is energy per unit of time. Power is work/time and it is measured in watts.
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
