# Do all gas molecules have the same kinetic energy support your answer? ### Do all gas molecules have the same kinetic energy support your answer?

So when two gases are at the same temperature, their molecules have the same average kinetic energy. However, an even more unexpected fact is that the mass of the molecules of one gas is different from the mass of the molecules of the other gas.

### Do all gas particles have the same energy?

Not all particles of gas in a sample have the same speed and so they do not have the same kinetic energy. The temperature of a gas is proportional to the average kinetic energy of the gas particles.

### Is the average kinetic energy of molecules the same for all gases at the same temperature?

Now here is an unexpected fact: the average kinetic energies of molecules of any gas at the same temperature are equal (since KE = 3/2kT, the identity of the gas does not matter).

### Do ideal gases have the same kinetic energy?

Molecules of an ideal gas at the same temperature have potentially different kinetic energies... but the same average kinetic energy.

### Do all of the air molecules in your room have the same kinetic energy explain your logic?

Explanation: The average kinetic energy at a given temperature will be the same value. A gas at room temperature - Some move faster, some move slower, and their average will always be the same at that temperature.

### Which gas has more kinetic energy?

Particles at the same temperature have the same average kinetic energy, so argon and nitrogen, which are at 20°C , are the gases with the lowest average kinetic energy. Nitrogen and helium, at 100°C , have the highest average kinetic energy because they have the highest temperature.

### Which has more energy oxygen or hydrogen?

The average velocity of hydrogen molecules is 4 times greater than that of oxygen molecules. It is important to note that although the average kinetic energy of all gases is the same at a particular temperature, the average velocity of the molecules is not.

### Do all molecules have same average kinetic energy?

n = the fraction of molecules. Larger molecular weights narrow the velocity distribution because all particles have the same kinetic energy at the same temperature. Therefore, by the equation KE=12mv2 K E = 1 2 m v 2 , the fraction of particles with higher velocities will increase as the molecular weight decreases.

### Is the average kinetic energy of a molecule at a given temperature is constant?

Since molecules are moving with different velocities, this means that they possess different kinetic energies. However, the average kinetic energy of molecules of a gas is directly proportional to the absolute temperature of gas.

### What is the kinetic energy of an ideal gas?

The internal energy of an ideal gas The result above says that the average translational kinetic energy of a molecule in an ideal gas is 3/2 kT. For a gas made up of single atoms (the gas is monatomic, in other words), the translational kinetic energy is also the total internal energy.
