Particles of a Gas

http://www.middleschoolchemistry.com/multimedia/chapter1/lesson5#air_has_mass_ball

• Particles of a gas have very little attraction for each other.

• They collide with each other and bounce off.• The space between molecules is made up of nothing.

Part A: Warming the air inside a bottle.

Part B:  Cooling the air inside a bottle.

What happened to the film of detergent solution when you placed the bottle in hot water?

What happened to the bubble when you placed the bottle in cold water?

Animation

• Red arrows represent the outside air pushing down on the bubble film.

• Heating the air makes the molecules move faster.• Collisions with the bottle and bubble film increase and become harder. 

• This pushes the bubble up.

Cooling a Gas

• Cooling the gas makes the molecules move more slowly.

• These slower moving molecules hit the bottle and bubble film less often and with less force.

• The molecules in the outside air are moving faster and push the bubble film inside the bottle.

Compare molecules in a solid, liquid, and gas (same temperature).

solid ­ particles are very attracted to one another, vibrate but can't move past one another, has definite volume and definite shape.

liquid ­ particles are attracted to one another, vibrate and can move past one another, have definite volume but not definite shape.

gas ­ particles are not attracted to one another much at all, move freely, can move past one another, particles spread out evenly to fill a container.

Take it Further

Imagine that you work at a party store during the summer.  You are going to ride home with the owner of the store whose car has been sitting in the hot sun all day long.  The owner tells you that you can take home a bunch of balloons, but advises you to not blow the balloons up all of the way.  Knowing what you do about the heating the molecules of a gas, explain why the owner's advise is wise.

When a thermometer is cooled, the red liquid inside the thermometer moves down.  This is mainly because:

Cold liquids sink so the color falls in the thermometer

Hot liquids are lighter so the liquid moves down the thermometer.

The molecules move faster, and get a little further apart allowing the liquid to lower

The molecules of the liquid move slower and get a little closer together.

When you heat a sample of a solid, the particles that make up the solid:

Get bigger

move faster

become more dense

slow down

If you put food coloring in room termperature water, the coloring spreads throughout the water.  The water causes the color to spread mainly because:

The water molecules are warm

The water molecules are attracted to the food coloring.

The water molecules are in motion

The water is more dense that the food  coloring.
