Joule's Law of Equivalence between Work and Heat: It states that the amount of heat produced in a conductor due to an electric current is directly proportional to the square of the current (I), the resistance (R) of the conductor, and the time (t) for which the current flows. It can be represented mRead more
Joule’s Law of Equivalence between Work and Heat: It states that the amount of heat produced in a conductor due to an electric current is directly proportional to the square of the current (I), the resistance (R) of the conductor, and the time (t) for which the current flows. It can be represented mathematically as:
Q = I²Rt
This law also implies that work and heat are interchangeable, in other words, work done on a system can be converted into heat, and vice-versa.
### Mechanical Equivalent of Heat:
The **mechanical equivalent of heat** is the amount of mechanical work that has to be expended to produce a unit of heat. It is a measure of the relationship between mechanical energy (work) and thermal energy (heat). The most common unit used to express this is **Joules per calorie**.
It is defined as the amount of work (in Joules) required to produce 1 calorie of heat. The mechanical equivalent of heat is approximately:
1 calorie = 4.18 Joules
It means that to produce 1 calorie of heat, 4.18 Joules of mechanical work is required. This establishes the equivalence between mechanical energy and heat energy.
