Question

What is the unit of heat and relation between them

Answer 1

Heya friend this is your answer...


As a form of energy, heat has the unit joule (J) in the International System of Units (SI). However, in many applied fields in engineering the British thermal unit (BTU) and the calorie are often used. The standard unit for the rate of heat transferred is the watt (W), defined as one joule per second.
Relationship between them are they have kinetic energy...



Hope it helps..

Answer 2

Answer:

Generally, in the SI system, all forms of energy are measured in terms of joules. Notably, heat is a form of energy, and therefore the SI unit of heat is also joules (J) which are defined as the amount of energy needed to raise the temperature of a given mass by one degree. Usually, 4.184 joules of heat energy is necessary to increase the temperature of a unit weight (say 1 g) of water from 0 degrees to 1 degree Celsius.

energy= joule

heat= joule (si units)

       =ML²T^-2

cgs=cal

1cal=4.18 joul
