What did James joule find out in his experiment?

Answer 1

James Prescott Joule (December 24, 1818 - October 11, 1889) was an English brewer and physicist, born in Salford, Lancashire. By studying the nature of heat, Joule discovered its relationship to mechanical work. This led to the theory of conservation of energy, which in turn led to the development of the first law of thermodynamics. The SI derived unit of energy which is called the joule, is named after him. Along with Lord Kelvin, he developed the absolute scale of temperature, made observations on magnetostriction, and found the relationship between the current through resistance and its dissipated heat, now called Joule's law.

Answer 2

James joule found out that heat is a form of energy. He wanted to create a different method of measuring energy. Until then the common usage was the BTU, which measured the amount of energy it takes to pick up one pound - 1 foot high.

Joule converted such task into degrees.

===========================

The BTU is the amount of energy it takes to raise the temperature of

one pound of water by 1 Fahrenheit degree.

It's the same energy as 1055 joules or 778 foot-pounds.

None of these things is ever converted into degrees. Degree is

not a unit of energy, in fact has no physical dimensions at all.
