Q

An English physicist who in the 19th century studied the nature of heat and its relationship to mechanical work. His work led to the law of conservation of energy. He is remembered for his work with lord kelvin in establishing the absolute scale of temperature. (Kelvin scale).

A

James Prescott joule

Q

The energy in a closed system is neither created or destroyed but may be transferred within the system or transformed from one form to another. In a closed system, the amount of energy is fixed.

A

Law of conservation of energy
