Kinetic Molecular Theory

Front 1

Solid- What determines volume and shape for solid? Describe how the particles in a solid are moving.

Back 1

Solids have a fixed shape and occupy a fixed volume. They move slowly with less energy, they only slightly move, and they are very close together.

Front 2

Liquid- What determines volume and shape for liquids? Describe how the particles in a liquid are moving.

Back 2

Liquids, because they flow, can occupy whatever shape their container has, so they do not have a fixed shape. Faster than a solid with medium energy and have medium space between each other.

Front 3

Gas- What determines volume and shape for gas. Describe how the particles in a gas are moving.

Back 3

Gases can also flow, so occupy the shape of their whole container. They do not have a fixed shape.They move fast with a lot of energy and have lots of space between them.

Front 4

What are the four main points of Kinetic Molecular Theory?

Back 4

1. All matter is made of particles

2. There is empty space between particles

3. Particles are constantly moving and colliding with each other and the walls of their container

4. Energy makes the particles move. The more energy they have faster and farther apart the particles get from each other

Front 5

What is Kinetic energy? What would be a way to give something more kinetic energy.

Back 5

Kinetic energy is the energy of motion. Movement of energy by shaking the container or by making particles in container hot.

Front 6

What is the different between thermal energy and temperature?

Back 6

Thermal- The total amount of movement.

Temperature- The average kinetic energy of the particles in an object.

Front 7

A hot pot touches a cool table. What direction does the heat flow?

Back 7

Hot to cold.

Front 8

When an object is given more thermal energy it will...expand or contract?

Back 8

Expand

Front 9

When an object has thermal energy taken away it will...expand or contract?

Back 9

Contract

Front 10

How do you change the physical state of a material? (Ex. solid to liquid, gas to solid).

Back 10

Melting, freezing, evaporation, condensation, deposition, and sublimation.

Front 11

What happens when the gas inside a container has less pressure than the gas outside the container?

Back 11

In Implosion!

Front 12

What happens when the gas inside a container has greater pressure than the gas outside the container?

Back 12

An explosion!

Front 13

Which state(s) of matter are compressible?

Back 13

Gas

Front 14

Which state(s) of matter are incompressible?

Back 14

Liquids and Solids

Front 15

An object may appear to be compressed, but its volume has not decreased. What happened to the object instead of compression?

Back 15

It deforms

Front 16

What are two factors that determine a fluid's viscosity? Explain how they determine the viscosity.

Back 16

Temperature because heat has high energy and cold has low energy. Particle size/shape because of flow rate.

Front 17

When you heat a liquid, what happens to the viscosity? What happens when you heat a gas?

Back 17

Liquid; viscosity decreases.

Gas; viscosity increases.

Front 18

When you cool a liquid,what happens to the viscosity? What happens when you cool a gas?

Back 18

Liquid; viscosity increases.

Gas; viscosity decreases.

Front 19

An adhesive fluid will stick strongly to itself or other objects?

Back 19

Other objects

Front 20

A cohesive fluid will stick strongly to itself or other objects?

Back 20

Itslef

Front 21

Is surface tension a property of adhesion or cohesion? It makes it appear like the liquid has a _____________________.

Back 21

Cohesion. It makes it appear like the liquid has a thin skin or membrane.
