Question

mechanical equivalent of heat lab reporth​

Answer 1

Explanation:

Mechanical equivalent of heat (J) = Amount of Work (W) / units of Heat (Q). substituting these values we get, Dimensional Formula of Mechanical equivalent of heat (J) = M0L0T-0 . we can also say Mechanical equivalent of heat (J) is dimensionless quantity.

Answer 2

Answer:

THE MECHANICAL EQUIVALENT OF HEAT

A calorie is defined as that amount of heat necessary to raise one gram of water by one degree Celsius. The equivalence of heat energy and mechanical energy was deduced by measuring the amount heat created when an object undergoes a known amount of work due to a non-conservative force.

Explanation:

The temperature rise of the cylinder is measured and then the amount of heat in calories necessary to produce the temperature rise is calculated. The amount of work done in joules is equated to the calculated heat in calories to obtain what is known as the mechanical equivalent of heat.
