Answer 1

Answer:

The Joule equivalent of heat is the amount of mechanical or electrical energy contained in a unit of heat energy. The factor is to be determined in this experiment. P V I = × . ... In SI units, 4186 Joules/kilocalorie J = .

Answer 2

Question-

write the joull's formula for the equivalence of work and heat?

Answer-

eqivalence of heat- in case of mechanical eqivalent of heat motion and heat are mutually interchangeable and that is in every situation,a given amount of work generate the same amount of heat,provided work energy is totally converted into heat energy

the mechanical enegy of heat is given by:

J=w/Q

W=amount of work expanded in the production of heat.

Q=amount of heat..

Extra information-

work-it is a measure of energy transfer that occur when the object is move over a distance by an external force at least part of which is aplied in the direction of displacement.

Heat-heat is a transfer of kinetic energy from one medium to another medium.

it also signify degree of hotness of temeparature.

hope it helps u..
