Gas Laws - Conceptual Science

What kind of relationship exists if one value increases the other value decreases (or vice-versa)?

Inverse relationship

What kind of relationship exists if one value increases the other value also increases (the opposite is true as well)?

Direct relationship

If a balloon is placed in a freezer the volume will _______. Which Gas Law describes this?

DECREASE ....... CHARLES'

What two variables are compared in Boyle's Law?

P & V at constant temperature

What two variables are compared in Charles' Law?

V & T at constant pressure

What two variables are compared in Gay-Lussac's Law?

P & T at constant volume

How do gases exert pressure on a container?

The molecules bounce off the sides of the container, creating pressure.

If MORE gas molecules created MORE collisions with the sides of a container, the there will be (more , less) pressure.

MORE

If you heat up a gas do the particles move faster or slower?

FASTER

STATE OF MATTER OF SOLIDS

Shape:

Volume:

Speed of particles:

Distance between particles

Attraction between particles:

Shape: definite

Volume: definite

Speed of particles: slow

distance: close together

Attraction between particles: strong attractive force between particles.

STATE OF MATTER OF LIQUIDS

Shape:

Volume:

Speed of particles:

Distance between particles

Attraction between particles:

Shape: not definite

Volume: definite

Speed of particles: faster than solids but slower than gases

distance: farther apart - can move/slide around each other

Attraction between particles: kind of attracted but not much

STATE OF MATTER OF GASES

Shape:

Volume:

Speed of particles:

Distance between particles

Attraction between particles:

Shape: indefinite

Volume: indefinite

Speed of particles: fast

distance: really far apart

Attraction between particles: almost no attraction

The temperature scale that chemists use that has no negative values.

KELVIN

ABSOLUTE ZERO

0 degrees Kelvin

How do you convert Celsius to Kelvin

Add 273 to Celsius temperature.

If you leave a basketball outside on a winter night, what would you expect the basketball to be like the next day? Why?

The basketball would be smaller in size because when the temp drops, the volume will also drop.

If I added Helium gas to a balloon, the volume would _________.

INCREASE

Where would there be more air pressure - sitting at your desk in at school or standing on top of a mountain?

Sitting at your desk. As you increase in altitude there is less air... which equals less pressure.

If there is less pressure on a gas the volume will _____. Which gas law states this?

INCREASE...... BOYLE'S LAW

If a beach ball is left out in the sun, its pressure and volume will both __________________. What gas laws state this?

Charles' and Gay-Lusaac's

If a balloon is released into the atmosphere, what will happen to its volume as it rises? What gas law states this?

The volume will increase due to a decrease in air pressure and it will rupture. This is Boyle's Law

If an aerosol can is heated enough, the can will explode. What gas law is this?

Gay-Lusaacs Law
