Which temperature scale provides a direct measure of the average kinetic energy of a substance?: Q: Which temperature scale provides a direct measure of the average kinetic energy of a substance?What is the name of the device used to measure gas pressure?Help? Thanks.; A: You have to use the Kevin scale for any energy calculations.The instrument used to measure pressure depends on the pressure. Very low pressures such as in vacuum operations use an ionisation gauge or a McCloed gauge. Near ambient pressures you can use a manometer. At very high pressures such as in a rocket engine you would need a pressure gauge or perhaps a strain gauge.

If the average kinetic energy of a substance changes what happens?: Q: A)its temperature changesB)it may change phaseC)thermal energy has been transfered into or out of the substanceD)all of these; A: The answer should be A.Average kinetic energy of a substance is related to the speed of the particles moving in it and the temperature of the substance.As the particles in the a substance moves faster, the average kinetic energy of the substance increases. So does the temperature.When a substance changes phase, the temperature will remain constant. This means that the average kinetic energy is also constant during this process. Hence, B is wrong.When thermal energy is being transferred out of the substance, one could understand it as taking out some particles out of the substance. So what is changed here? I would think that the total kinetic energy is being changed, since some particles have been taken away. But the taking away of the particles would not affect the speed of the remaining particles. The AVERAGE kinetic energy should remain unchanged. Hence, C is also wrong.

In which phase of a substance do its particles have the greatest average kinetic energy?: Q: In which phase of a substance do its particles have the greatest average kinetic energy?In Which phase does the substance have the highest potential energy?; A: I'll just throw out there that it seems likely a plasma would have the highest kinetic energy. I'm not sure if that is one of the choices, depending on the context of the original question.
