Pressure Change in Gas Due to Temperature Increase

In a closed container, a sample of gas is heated from 25°C to 100°C, and the pressure is measured before and after the temperature change. The initial pressure of the gas at 25°C is 1.00 atm. Assuming the volume of the gas remains constant and that the gas behaves ideally, what is the final pressure of the gas at 100°C? Use the ideal gas law to determine your answer.

The ideal gas law states that PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the ideal gas constant, and T is the absolute temperature in Kelvin. For this problem, we can relate the initial and final states using the formula: P1/T1 = P2/T2.
