The average kinetic energy of translation of oxygen molecules in the gas is 5.05 × 10⁻²¹
The given data is
n = 2
v = 20
P = 92
K.E = 3 / 2 KbT
= 3 / 2 PV / N
= 3 / 2 Pv / nNa
K.E = 3 / 2 × 9 × 1.013 × 10⁵ × 20 × 10⁻³ / 2 × 6.022 × 10²³
K. E = 5.05 × 10⁻²¹ J
<h3>Average kinetic energy</h3>
The average kinetic energy (K) is equal to one half of the mass of each gas molecule times the RMS speed squared
Hence, the average kinetic energy is 5.05 × 10⁻²¹ J

The answer is B.
The answer is C. Overpopulation.
Because life expectancy has increased, the number of people that are alive on Earth at one time has also increased. In many regions of the world, more babies are being born than the number of people dying, causing the populations to grow, and as populations increase, the risk of overpopulation becomes feasible.
Hope this helps! :)
