Question

what is meant by joule; s constant

Answer 1

The Joule constant J is defined as the number of joules equivalent to one calorie. This constant is sometimes called the "mechanical equivalent of heat", because early experiments usually involved the conversion of mechanical energy to heat.

Answer 2

Answer:

Joule's constant is the relationship between kinetic energy and heat. Kinetic energy is usually expressed as force times distance (Newton-meters), which physicists call work, but it is interchangeable with kinetic energy. The most recent value given is 4.1868 Newton-meters per calorie.
