Video transcript

Hi everyone here we have a question asking us to consider a 2. vessel build with 02 gas, oxygen gas. If the temperature is decreased from 25°C to 5°C and the volume is held constant, how would this affect the average kinetic energy of the gas molecule? So the average kinetic energy is directly proportional to temperature And it is directly proportional. So if our temperature is going up, our average kinetic energy is gonna go up. If our temperature is decreasing, our average kinetic energy is decreasing, we are going from 25°C to 5°C, so we are decreasing. So our average kinetic energy is also decreasing. And that is our final answer. Thank you for watching. Bye.

Textbook Question

You have an evacuated container of fixed volume and known mass and introduce a known mass of a gas sample. Measuring the pressure at constant temperature over time, you are surprised to see it slowly dropping. You measure the mass of the gas-filled container and find that the mass is what it should be—gas plus container—and the mass does not change over time, so you do not have a leak. Suggest an explanation for your observations.
