What's one example of pressure?

Multiple Choice

On a really cold day, would the pressure in your tires be higher or lower than on a hot day?

• Higher

• Lower

Multiple Choice

Would the pressure be larger inside of a large balloon or a small balloon if the amount of helium and temperature are constant?

• Large balloon

• Small balloon

Multiple Choice

The pressure __________ as you remove gas from a balloon.

• Increases

• Decreases

Multiple Choice

As temperature increases, volume ___________

• increases

• decreases

Multiple Choice

What causes the pressure to increase if more gas particles are added to a closed container?

• an increase in the number of collisions between the gas and the container walls

• a decrease in the volume of the container

• a decrease in the size of each particle as the number of particles increases

• an increase in the number of collisions between air particles and the outside of the container

Multiple Choice

When first blown up, a balloon is firm because of the air pressure inside it. However, after time, the balloon becomes soft as the air pressure inside drops. What could have caused the air pressure to decrease?

• increase in air temperature

• decrease in the balloon's volume

• decrease in the number of air particles as they leaked out of the balloon

• a chemical reaction between the air particles and the balloon

Multiple Choice

A gas has a volume of 15 L, a temperature of 300 K, and an unknown initial pressure. Then, the gas expands to 30 L, remains at 300 K, and has a pressure of 300 kPa. What was the initial pressure of the gas?

• 150 kPa

• 600 kPa

• 330 kPa

• 570 kPa

Multiple Choice

According to Charles’s law, the relationship between the temperature and the volume of a gas is...

• direct

• inverse.

• exponential.

• inverse square.

Multiple Choice

When the temperature of a gas in closed container is increased, the pressure increases.
