### Who invented joule?

**James Prescott Joule**, (born December 24, 1818, Salford, Lancashire , England—died October 11, 1889, Sale, Cheshire), English physicist who established that the various forms of energy—mechanical, electrical, and heat—are basically the same and can be changed one into another.

### What is the dimension of force and momentum?

The dimensional formula for the moment of force is .

### What are the dimensions of a and b/in Vander Wall's equation P A v 2 )( VB )= RT?

The Van der Waals equation of state for some gases can be expressed as: (P+aV2)(V−b)=RT, where P is the pressure, V is the molar volume, and T is the absolute temperature of the given sample of gas and a, b and R are constants. The dimensions of a are: (A) **ML5T−2**. **(B) ML−1T−2**.
