Maxwell and Boltzmann have shown that actual distribution of molecular speeds depends, on temperature and molecular mass.
What do you mean by most probable velocity?

Maxwell and Boltzmann have shown that actual distribution of molecular speeds depends on temperature and molecular mass. At the same temperature which will move faster, N_2 or Cl_2 ?

What do you mean by drift velocity?

Draw the Maxwell- Boltzmann distribution showing all the molecular speeds.

The term order and molecularity are common in chemical kinetics. What do you mean by order and molecularity?

What do you mean by the center of mass of a rigid body?

What do you mean by mass-energy equivalence? Give example.

The order of a chemical reaction can be zero and even a fraction but molecularity cannot be zero or a non-integer. What do you mean by the order of a reaction ?

We have common experience that a thin thread breaks if pulled at its ends. Also a thin metalic wire, when pulled at the ends elongates and then contracts, when released. What do you mean by elasticity?

One mole is the amount of substance that contains as many elementary particles as 12 g of _^12C isotope of carbon. What do you mean by molar mass of a compound?
