Determine whether each of the following changes will increase, decrease, or not affect the rate with which gas molecules collide with the walls of their container: (a) increasing the volume of the container (b) increasing the temperature (c) increasing the molar mass of the gas

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.
