QUESTION:
Problem 14E
Why does the pressure of gas enclosed in a rigid container increase as the temperature increases?
ANSWER:
Solution
Step 1 of 2
The gas inside the rigid container can be considered as ideal gas,
The state of the ideal gas can be determined by the ideal gas equation,
Given by
PV=nRT
Where
P, V and T are the pressure , volume and temperature of the gas respectively, R is the universal gas constant and n is the number of moles of gas.
Since here the container is Rigid container, volume and mass of the gas remains constant.
Hence here it is given;volume is constant, temperature and pressure is related as.(R is constant and n are constant)
Therefore, at constant V
That is, the pressure of the gas is directly proportional to the temperature at constant volume, which is referred as Charles's Law.
