This theory explains the behavior of particles in matter.

KMT

100

 In this state, particles spread out to fill the shape of their container.


  • What is a gas?
100

 Ice cubes stay in a fixed shape because particles in a solid can only do this.


vibrate in place.

100

This state of matter flows easily because its particles can slide past one another.

  • ?

What is liquid

100

Gas particles can move freely because they are far apart and have ___________amount of attraction to each other.

Negligible/zero

200

KMT states that all matter is made up of

Particles

200

When particles move from a liquid state to a gas state, this process occurs.


  • What is evaporation?
200

A drop of food coloring spreads in water because of this KMT principle.


  • What is diffusion?
200

You smell fresh cookies baking in the kitchen because of this particle behavior.

dIFFUSION

200

When a basketball is left outside in winter, it feels deflated because of this particle behavior.


particles slow down and exert less pressure

300

According to KMT, particles are always doing this, no matter the state of matter

Moving

300

In this process, particles move from a gas state to a liquid state.


  • What is condensation?
300

The state of matter where particles are packed closely together but can still vibrate

Solid

300

When you smell perfume from across the room, this principle of KMT is at work.

dIFFUSION

300
  • Ice cream melts on a hot day because heat energy ________________ particles

increases the movement of particles.

400

When temperature increases, the particles in a substance do this.


move faster

400

In this process, particles move from a gas state to a solid state.

Desposition

400

Why does railway tracks expands when heated

Energy causes them to vibrate more and move farther apart

400

Frost forms on a window in winter because water vapor particles in the air

lose energy and freeze (deposit)

400

A pressure cooker cooks food faster because the high pressure inside causes particles to do this.

Particles collide more frequently and transfer heat faster as a result food is cooked faster.

500


This happens to the volume of a gas when pressure increases, assuming temperature stays constant.


Decreases

500

The term for when particles move directly from a solid to a gas.


  • What is sublimation?
500

When heated, a balloon expands because gas particles do this.

move faster and spread out

500

A tire feels flat on a cold day because gas particles do this when cooled.

move slower and contract.

500

When you heat a thermometer, the liquid inside rises because the liquid particles

move faster and spread out
