Concept explainers
Interpretation: The new pressure of the gas needs to be determined.
Concept Introduction:
The ideal gas equation is represented as follows:
Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature of the gas.

Answer to Problem SII4RE
Explanation of Solution
Given Information:
The initial pressure and temperature of the gas sample in rigid container is 3.0 atm and 350 K respectively. Also, the final temperature is 450 K.
Calculation:
The ideal gas equation is as follows:
For the given gas sample, pressure and temperature are changing at constant volume and number of moles as gas is present in a rigid container thus,
On rearranging,
Putting the values,
Thus, the new pressure of the gas is
