The average kinetic energy of molecules in a gas at temperature T is 1.5 kT. Find the temperature at which the average kinetic energy

True In an inelastic collision, the final kinetic energy is always less than the initial kinetic energy of the system. This is because in such collisions, there is always a loss...

The correct answer is (b) momentum

(a) the initial kinetic energy is equal to the final kinetic energy  Explanation:  The initial kinetic energy before the collision and the final kinetic energy after the collision will remain the same....

(b) the final kinetic energy is less than the initial kinetic energy  Explanation:  If the collision is perfectly inelastic the deformation of the bodies during the collision is permanent and the part of...

(a) Assume the third number = x According to question 2 × 280 + x + 178.5 × 2 = 281 × 5 or, 560 + x + 357 = 1405 or, x +...

(d) Third number = (436 × 5) – (344 × 2 + 554 × 2) = 2180 – 1796 = 384

(4) Vanderwaal constant (a) ∝ forces of attraction.

The gas pressure would gradually become zero as molecules will gradually slow down and ultimately settle down due to constant loss of energy

K = 8.62 x10–5 eV/k K.E. of H2 molecules = 3/2 KT Energy released, when atom goes from ground state to no = 3 =>13.6 (1/1 – 1/9) => 3/2 KT = 13.6(1/1...

Helium is monoatomic gas .   So its average kinetic energy per molecule (E) = 3/2*kT, where k =R/N ( Boltzman constant), N = Avogadro's Number. So N =(3/2)*(RT)/E
