Question

Which of the following statements is true for ideal gases, but is not always true for real gases?
Choose all that apply.

There are no attractive forces between molecules.

Pressure is caused by molecule-wall collisions.

Replacing one gas by another under the same conditions, has no effect on pressure.

Average molecular kinetic energy increases with temperature.

Which of the following statements is true for real gases?
Choose all that apply.

Attractive forces between molecules cause an increase in pressure compared to the ideal gas.

As molecules increase in size, deviations from ideal behavior become more apparent at relatively low pressures.

Attractive forces between molecules cause a decrease in pressure compared to the ideal gas.

As molecules increase in size, deviations from ideal behavior become more apparent at relatively high pressures.

Explanation / Answer

1) The correct statements are

There are no attractive forces between moleucles

Replacing one gas by another under same conditions has no effec on pressure

2) The correct statements are

attractve forces between moleucles cause a decrease in pressure compared to ideal gas

As molecules increase in size , deiations from ideal behaviour is more apparent at relatively high pressures.
