All pressure-volume-temperature relationships for gases can

Last updated: 8/4/2022

All pressure-volume-temperature relationships for gases can be combined into a single relationship known as the combined gas law. This expression can be used when looking at the effect of changes in two of these variables on the third as long as the amount of gas (number of moles) remains constant. To use the combined gas law properly, you must always express the temperatures in kelvins. The combined gas law can be represented as follows: P₁V₁ Ti = P2V₂ T2 V₂ = 38.1 L Consider 4.40 L of a gas at 365 mmHg and 20. °C. If the container is compressed to 2.10 L and the temperature is increased to 31 °C, what is the new pressure, P2, inside the container? Assume no change in the amount of gas inside the cylinder. Express your answer with the appropriate units.
