Acylinder of oxygen gas is cooled from 300k to 150k by what factor does the average kinetic energy of the oxygen molecules in the cylinder decrease

The factor by which the average kinetic energy of the oxygen molecules in the cylinder decreases is '0.5'.

Explanation:

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

where,

K = Average kinetic energy

R = Gas constant

T = Temperature of the system

= Avogadro's number

Average kinetic energy of oxygen gas molecule at 300 K.

..[1]

Average kinetic energy of oxygen gas molecule at 150 K.

..[2]

[1] ÷ [2]

The factor by which the average kinetic energy of the oxygen molecules in the cylinder decreases is '0.5'.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
