Two gases A and B of molecular masses m1 and m2 respectively are kept at same temperature, pressure and volume. Find the ratio of their (i) internal energies, (ii) number of molecules, (iii) partial pressures and (iv) rms speed of A that of B.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

Two cars collide, lock bumpers and move together after the collision.this collision is known as perfectly inelastic collision.
