Question

How is the SI unit of heat related to the unit calorie?

Answer 1

Explain the Units of Energy:

1. We know that the SI unit of heat is joule or $J$.
2. One joule can be defined as the force applied in Newton to displace a body of unit mass through $1m$.
3. A calorie is another unit of energy.
4. The amount of heat required to increase the temperature of $1gram$ of water by $1°C$ can be defined as one calorie.
5. The relation between joules and calories is,

$1cal=4.184J$
