Latent Heat is defined as the heat absorbed or released per unit mass of the substance when the substance changes its phase at the constant temperature.

Latent heat of fusion is defined as the quantity of heat in calories required to transform 1 gm of solid substance at its melting point into liquid of the same temperature.

Mathematically,
Latent heat of fusion (L) = Heat (Q) / mass (m)

Dimensional formula of Heat(Q) = M¹L²T^-2
Dimensional formula of mass = M¹L⁰T⁰

Putting these values in above equation we get,
Dimensional Formula of Latent Heat = M⁰L²T^-2
SI unit of Latent Heat is Joule kg^-1

Note:- Dimensional formula of latent heat of fusion is same as Latent heat. Similarly SI unit of Latent heat of fusion is same as Latent Heat.

The Gravitational Potential at a point in a gravitational field is defined as the amount of work done in bringing a body of unit mass from infinity to that point without acceleration.The gravitational potential at a point is always negative, it is maximum (= 0 ) at infinity.

Mathematically,

Gravitational Potential at a point (V) = Work done (W) / mass (M)

Dimensional Formula of Work= M¹L²T^-2
Dimensional formula of  Mass = M¹L⁰T⁰

Putting these values in above equation we get,
The Dimensional formula of Gravitational Potential is M⁰L²T^-2.
The SI unit of Gravitational Potential is J kg-1.

In physics weight is defined as the product of mass and acceleration. It is the force with which the earth attracts the body towards its centre.

Mathematically,
Weight = Mass x Acceleration.

Dimensional Formula of Mass = M¹L⁰T⁰
Dimensional Formula of Acceleration = M⁰L¹T^-2

Putting these values in above equation we get,

Dimensional Formula of Weight = M¹L¹T^-2
SI Unit of Weight is newton (N) or Kg.m.s^-2

Temperature of a body is defined as the property that determines whether or not a body is in thermal equilibrium with other bodies. In other words Temperature is degree of hotness or coldness in a body and is a measure of heat energy level. In Thermodynamics temperature is measured in Kelvin (K). Kelvin is one of the seven base unit in the International System of Unit(SI)

So,
Dimensional Formula of Temperature = M⁰L⁰T⁰K¹
SI Unit of Temperature is K(Kelvin).

Heat is defined as the form of energy that is transferred across the boundary of a system at a given temperature to another system at a lower temperature by virtue of the temperature difference between the two system.

Mathematically,
Heat = Energy

Dimensional formula of Energy = M¹L²T^-2

Putting these values in above equation we get,
Dimensional Formula of Heat = M¹L²T^-2
SI unit of Heat is Joule (J)
