Answer:
320 K
Step-by-step explanation:
Given:
Number of moles of gas , n = 3
Dimensions of the rectangular container = 0.2 m × 0.2 m × 0.4 m
Thus,
Volume of the container = 0.2 m × 0.2 m × 0.4 m = 0.016 m³
Pressure inside the container, P = 498,840 N/m²
Now,
From the ideal gas law, we have
PV = nRT
here,
T is the temperature
R is the ideal gas constant = 8.314 J / (mol·K)
on substituting the values, we get
498,840 × 0.016 = 3 × 8.314 × T
or
T = 320 K
Hence, the pressure inside the container is 320 K
