Question

which of the follwing sentences regrading the kinetic molecular theory fo gases are correct. correct the false statements.

1. the average kinetic enegry of a collection of gas molecules at a given temperature is proportional to m^(1/2).

2. the gas molecules are assumed to exert no forces on each other.

3. all the molecules of a gas at a given temperature have the same kinetic energy.

4. the volume of the gas molecules is negligble in comparison to the total volume in which the gas is contained.

5. all gas molecules move with the same speed if they are at the same temperature.

Answer 1

i am not sure about 1, 2, 4

Answer 3

anyone plz help ?

Answer 4

2 and 4 are true for ideal gases

The temperature of a gas depends on its average kinetic energy avg(1/2mv 2) = 3/2kT . In other words, the energy of an ideal gas is entirely kinetic

Answer 5

oh ok thanku
