Description

Introducing the kinetic theory of matter and the states of matter.

Day 3: October 27/28 Objective: SWBAT use the Kinetic Theory model to illustrate and account for the physical properties of a substance Homework: page 38 Warm up: What is the smallest thing that humans are made of?

Homework: page 38

Warm up: What is the smallest thing that humans are made of?

Write in homework NOW turn to page 38 Create your own example to explain the kinetic theory of matter. You must detail how it represents the movement of particles and the changes with more/less energy

Kinetic Theory of Matter Idea that explains A concept movement All stuff in the universe

Kinetic Theory of Matter All things are made up of small particles too small to be seen that are in constant motion The more energy you have, the more motion you have

All things are made up of small particles too small to be seen that are in constant motion

The more energy you have, the more motion you have

Thinking Questions What was added to the solid to cause it to melt? What would you take away from the system to make it re-solidify? How is a liquid transformed into a gas? How is a gas transformed into a liquid? In the popcorn and margarine model, what does the margarine represent? What do the popcorn kernels represent?

What was added to the solid to cause it to melt? What would you take away from the system to make it re-solidify?

How is a liquid transformed into a gas?

How is a gas transformed into a liquid?

In the popcorn and margarine model, what does the margarine represent? What do the popcorn kernels represent?

Key Takeaways Popcorn = atoms Butter = bonds between atoms Exploding popcorn kernel = atoms going to gas phase the atoms are always moving the more energy they have the faster they move When they get enough energy, the substance changes states of matter (i.e. liquid to gas)

Popcorn = atoms

Butter = bonds between atoms

Exploding popcorn kernel = atoms going to gas phase

the atoms are always moving

the more energy they have the faster they move

When they get enough energy, the substance changes states of matter (i.e. liquid to gas)

Surface area: Fixed

When heated: Expands Very little

Diffusion: Almost impossible

Liquid H 2 0 = water Bonds: longer and looser Movement: flexible, fluid (bend without breaking) Density: High Volume: Fixed volume Surface area: Fixed When heated: expands tiny bit Diffusion: happens easily

H 2 0 = water

Bonds: longer and looser

Movement: flexible, fluid (bend without breaking)
