Question

Read the following statements and decide which one(s) would not be correct. Check all that apply.

Group of answer choices

Gas molecules collide with each other without loss of energy.

Gas molecules collide with the container walls without loss of energy.

The pressure of a gas at constant temperature in a sealed container will gradually decrease.

Because of the relationship between temperature and average molecular speed, the temperature of a gas would drop if energy were lost in collisions.

Friction does not slow down gas particles and cause them to stop moving.

Answer 1

The incorrect statements include the one about the pressure of a gas at constant temperature in a sealed container decreasing over time, and the notion that friction can stop gas particles. The kinetic molecular theory explains why these are misconceptions. The incorrect statements are The pressure of a gas at constant temperature in a sealed container will gradually decrease and Friction does not slow down gas particles and cause them to stop moving.

Step-by-step explanation:

Reviewing the given statements, there are a few that would not be correct according to the kinetic molecular theory of gases.

• The statement that the pressure of a gas at constant temperature in a sealed container will gradually decrease is not correct. According to Amontons's law, if the temperature remains constant, the pressure should also remain constant as long as the volume doesn't change.
• Additionally, the statement that friction does not slow down gas particles and cause them to stop moving is a misconception, as in an ideal gas, there are no forces of interaction, including friction, between gas particles, but in real gases, interactions do happen and can affect motion.

Statements about gas molecules colliding without loss of energy and temperature affecting molecular speed are in line with the principles of the kinetic theory of gases.
