Which container will have a lower pressure?

they both have the same pressure

Gas pressure is caused by

Gas molecules hitting the walls of a container

Gas molecules reacting with other gas molecules

Gas molecules hitting other gas molecules

The temperature of gas is held constant, while its volume is decreased. The pressure exerted by the gas on the wall of the container increases, because its molecules

Strike the walls more frequently

Strike the walls with higher velocities

Strike the walls with large farce

Are in contact with the walls for a shorter time

Gas pressure decrease when

air particles collide each other and the wall of container more often

What about gasses can be measured?

Pressure, Temperature, Volume, and Moles

Temperature, Volume, and Pressure

Explain what would happen to the column of mercury in the barometer as shown if the atmospheric pressure fell.

As the pressure falls, the column of mercury will drop lower.

As the pressure falls, the column of mercury will remain unchanged.

As the pressure falls, the column of mercury will rise higher.

As the pressure falls, the density of the mercury will increase.

Which container will have a lower pressure?

they both have the same pressure

When a cold tire is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the

air molecules speed up and collide with the tire walls more often

air molecules hit the walls of the tire less frequently

rubber in the tires reacts with oxygen in the atmosphere

air molecules diffuse rapidly through the walls of the tire.

When the volume of air in a syringe is reduced at constant pressure, the pressure of in the syringe increases because

the air molecules collide with the walls of the syringe more frequently.

the air molecules collide with the walls of the syringe more vigorously.

the air molecules collide with the walls of the syringe more frequently and more vigourously.

the number of air molecules in the syringe increases.

Gas pressure is caused by

gas molecules colliding with surfaces

gas molecules condensing to a liquid

gas molecules hitting other gas molecule

A sample of a gas in a cylinder is shown. If the temperature is kept constant and the piston moves down to decrease volume, the pressure increases because the gas particles...

Collide more often within the container

Lose velocity within the container
