Question

what is CGS and SI unit of heat state the relation between them​

Answer 1

Answer :-

Heat Energy -

The kinetic energy due to random motion of the molecule of a substance is called as heat energy.

S.I. unit - Joule (J)

C.G.S. unit - Calorie (cal)

Relationship between C.G.S. and S.I. unit of heat -

1 Calorie = 4.186 J or 4.2 J(approx.)

1 kilo- calorie = 1000 calorie = 4200 J(approx.)

1 J = 0.24 cal

$\star$ The heat capacity of a body is the amount of heat required to raise its temperature by 1°C or 1 K.

$\star$ Heat capacity of a body when expressed for unit mass is called specific heat capacity.

$\star$ The quantity which determines the flow of heat between two bodies when the two are in contact, is known as temperature.
