What are the three main properties of gases?

• No fixed shape, expand to fill container, low density.

• Fixed shape, compressible, high density.

• No expansion, high viscosity, solid state.

• Constant volume, low temperature, high pressure.

How do gases behave when pressure is increased?

• Gases decrease in volume when pressure is increased.

• Gases increase in volume when pressure is increased.

• Gases remain unchanged when pressure is increased.

• Gases condense into liquids when pressure is increased.

What is the density of a gas?

• The density of a gas is its volume multiplied by its mass.

• The density of a gas is its mass divided by its volume.

• The density of a gas is its mass plus its volume.

• The density of a gas is its temperature divided by its pressure.

Can you name a gas that is lighter than air?

• Carbon Dioxide

• Nitrogen

• Oxygen

• Helium

What happens to gas particles when they are heated?

• Gas particles become denser and settle down when heated.

• Gas particles lose energy and slow down when heated.

• Gas particles move faster and collide more frequently when heated.

• Gas particles change into a liquid state when heated.

How does temperature affect the density of a gas?

• Density remains constant regardless of temperature changes.

• Lower temperature decreases density of a gas.

• Temperature inversely affects the density of a gas; higher temperature decreases density, while lower temperature increases density.

• Higher temperature increases density of a gas.

What is the relationship between pressure and volume in gases?

• Pressure and volume are directly related in gases.

• Pressure and volume are inversely related in gases.

• Increasing volume increases pressure in gases.

• Pressure remains constant regardless of volume in gases.

What is an example of a gas law?

• Charles's Law

• Boyle's Law

• Ideal Gas Law

• Avogadro's Law

How do gases fill a container?

• Gases remain in one corner of the container.

• Gases only fill the bottom of the container.

• Gases condense to a liquid in the container.

• Gases fill a container by expanding to occupy all available space.

What is the term for the amount of space a gas occupies?

• Volume

• Temperature

• Density

• Pressure
