In a room, the different molecules making up the air have, on average, the same kinetic energy. This is governed by the ideal gas law and the distribution of kinetic energies within a gas at a particular temperature. Despite differences in mass and speed, the average kinetic energy remains constant for a given temperature.

The different molecules that make up the air in a room have on average the same kinetic energy how does the speed of the different air molecules depend on their masses?

According to the kinetic theory of gases, the average kinetic energy of gas molecules in a room is proportional to temperature, not mass. However, the speed of individual gas molecules is inversely proportional to their mass - lighter molecules will move faster on average compared to heavier molecules at the same temperature. This is because kinetic energy is distributed among all molecules, and lighter molecules can move faster with the same amount of kinetic energy.


What is proportional to the average kinetic energy of the atoms and molecules that make a substance?

The temperature of the substance is proportional to the average kinetic energy of its atoms and molecules. The higher the temperature, the greater the average kinetic energy. This relationship is described by the kinetic theory of gases.


What happens to kenetic energy as temperature increases?

The average Kinetic energy of the atoms in the sample will increase as the sample is heated.


What describes the average kinetic energy of the particles that make up a substance?

The average kinetic energy of the particles that make up a substance is a measure of the average speed at which these particles are moving. It is directly proportional to the temperature of the substance. As temperature increases, the average kinetic energy of the particles also increases.


Define kinetic energy in terms of temperature?

The reverse is usually done .... Define temperature in terms of KE. The temperature of a body is proportional the the average Kinetic Energy of the particles (molecules or atoms) that make up the body. Can't be done the other way because a car traveling at 60 miles per hour has Kinetic energy which has nothing to do with temperature. The car doesn't care if is 100 degrees or 20 degrees.

Ok, i am currently on this subject right now and im in 7th grade, so, here goes... the temperature affects the kinetic energy of water molecules by slowing the molecules as the temperature gets cooler and when u heat up the water, the molecules spread out and bounce around. the colder, the more stuck together, more still and close they r. when they r warmer they r the complete opposite. hope that's good enough (:
