Pressure is measured in units of...

• atmospheres

• cm²

• newtons

• particles

What relationship does this demonstrate?

• as volume decreases, pressure increases

• as volume increases, pressure decreases

• as volume increases, pressure increases

• as volume decreases, pressure decreases

Why does adding more particles increase pressure?

• more collisions on the surface of the tire

• more mass inside the tire

• more space between the particles

• particles collide and combine into larger particles

What concept on pressure does the image show?

• adding particles increases pressure

• more mass increases pressure

• larger particles increases pressure

• more space between particles increases pressure

How does heat affect pressure?

• increasing heat causes an increase in pressure

• increasing heat causes a decrease in pressure

• increasing heat causes particles to explode

• increasing heat causes particles to catch on fire

Why does changing temperature cause a change in pressure?

• particles collide harder and more often with the sides of the container

• particles burn the sides of the container

• particles enlarge the hotter they become

• particles get too hot and turn into pure energy
