What happens to gases or liquids that are less dense when surrounded by more dense substances?

• They float upward

• They sink downward

• They disappear

• They change color

Lily is working in a science lab and wants to know if a certain gas can catch fire when exposed to a flame. What does the property of flammability describe?

• Whether a gas can catch fire

• Whether a gas is colorful

• Whether a gas is heavy

• Whether a gas is cold

What effect do non-flammable gases have on a fire when present in large amounts?

• They put out the fire

• They make the fire hotter

• They turn the fire blue

• They make the fire spread faster

Why might a science class compare how easily various gases catch fire?

• To better understand what makes a substance flammable

• To identify which gas is the heaviest

• To determine which gas dissolves in water

• To see which gas is the brightest
