Heat Energy ||Mechanical Equivalent OF Heat||Specific Heat||Thermal Capacity || Latent Heat

Heat Energy ||Mechanical Equivalent OF Heat||Specific Heat||Thermal Capacity || Latent Heat

Deduce the dimensional formulae for the following physical quantities: Mechanical equivalent of heat.

We need mechanical equivalent of heat because

The S.I value of Mechanical equivalent of heat is:

Define mechanical equivalent of heat. What is its value ?

State Joule's law of equivalence between work and heat. Hence define mechanical equivalent of heat.

State Joule's law of equivalence between work and heat. Hence define mechanical equivalent of heat. Give its value.

Find the value of Joule's mechanical equivalent of heat from the following data: density of hydrogen at NTP is 0.09kgm^(-3) , its specific heat capacity at constant pressure =3400 cal kg^(-1)K^(-1) and ratio of specific heat capacities (gamma)=1.4 .

m' grams of a gas of a molecular weight M is flowing in a isolated tube with velocity 2v. If the gas flow is suddenly stopped the rise in its temperature is ( gamma= ratio of specific heats, R=universal gas constant, J=Mechanical equivalent of heat)
