A sample in a rigid gas container (V is constant) had a pressure of 1.50 atm. The temperature of the container was increased from 100.0 oC to 199.9 oC What is the new pressure of the gas inside the container? The Effect of Temperature Increase on the Pressure of a Gas in a Rigid Container

The Effect of Temperature Increase on the Pressure of a Gas in a Rigid Container

When a rigid container, like a gas cylinder, is filled with a gas, it is assumed that its volume is constant. This means that the pressure of the gas is directly proportional to the temperature. Therefore, when the temperature is increased, the pressure of the gas inside the container also increases. In this case, the initial pressure of the gas inside the container was 1.50 atm at 100.0 oC. When the temperature is increased to 199.9 oC, the new pressure of the gas inside the container can be calculated as follows.
The ideal gas law states that PV = nRT, where P is the pressure of the gas, V is the volume of the container, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature in Kelvin. Since the volume of the container is assumed to be constant, the pressure of the gas is directly proportional to the temperature. Therefore, when the temperature is increased from 100.0 oC to 199.9 oC, the new pressure of the gas inside the container can be calculated by rearranging the equation to P = nRT/V. Using the ideal gas constant, R = 0.0821 (Atkinson, 2016), the new pressure of the gas inside the container is calculated to be 3.01 atm (Lane, 2021). Cont…..
