Video transcript

everyone in this example, we need to determine which of the following factors below affects the average kinetic energy of gasses. So we should recall our formula for the kinetic molecular theory of gasses que, which is equal to three halves multiplied by r gas constant. R divided by our avocados number represented by N. A. Here and then this quantity is multiplied by temperature which should be in kelvin. And so as you can see, we have temperature, that's not in the fraction. So we would say that our kinetic energy of our gas is is directly related to temperature. And so as our temperature changes are, kinetic energy will change in the same fashion because of this direct relationship. And so that means we can confirm that choice. C. Is the only correct answer to complete this example. So I hope that everything I reviewed was clear. If you have any questions, please leave them down below and I will see everyone in the next practice video.

At an underwater depth of 250 ft, the pressure is 8.38 atm. What should the mole percent of oxygen be in the diving gas for the partial pressure of oxygen in the mixture to be 0.21 atm, the same as in air at 1 atm?

Textbook Question

A quantity of N2 gas originally held at 5.25 atm pressure in a 1.00-L container at 26°C is transferred to a 12.5-L container at 20°C. A quantity of O2 gas originally at 5.25 atm and 26°C in a 5.00-L container is transferred to this same container. What is the total pressure in the new container?

Textbook Question

A sample of 3.00 g of SO21g2 originally in a 5.00-L vessel at 21 °C is transferred to a 10.0-L vessel at 26 °C. A sample of 2.35 g of N21g2 originally in a 2.50-L vessel at 20 °C is transferred to this same 10.0-L vessel. (a) What is the partial pressure of SO21g2 in the larger container?

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.
