Answer:
2.At a given temperature, the KE of all gases is the same.KE depends only on Kelvin temperature
Explanation:
The kinetic molecular theory of gases provides a succint expalantion and insight into the behaviour of gases. The assumptions of the theory are stated below:
- Gases are made up of large number of identical molecules which are moving at different speeds.
- Spaces occupied by molecules of gases are negligible compared to the volume of the container.
- Molecules of gases are independent of one another.
- The molecules collide with themselves and the walls of the container elastically.
- The temperature of a gas is a measure of only the average kinetic energy of the molecules.

Answer:
0.64 mol
Explanation:
Using ideal gas equation as follows;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question;
P = 0.72atm
V = 22 L
T = 30°C = 30 + 273 = 303K
n = ?
Using PV = nRT
n = PV/RT
n = (0.72 × 22) ÷ (0.0821 × 303)
n = 15.84 ÷ 24.88
n = 0.64 mol
