Answer:
All the gases have the same number of molecules.
Answer:
Option H
Explanation:
We can get the temperature of the gas by applying ideal gas law,
PV = nRT
Here, P = Pressure of the gas
V = Volume of the gas
n = Number of moles
R = Gas constant
T = Temperature
By substituting the values in the given equation,
5.40 × 120 = 4 × 0.0821 × T
648 = 0.3284T
T = 
T = 1973.20
≈ 1973 K
Therefore, temperature of the gas is 1973 °K
Option H will be the answer.
