Inertia, States Of Matter 2-2

Question 1

Low and High inertia

Answer 1

A small pebble rolling down a hill has low inertia. A large Boulder rolling down a hill has high inertia.

Question 2

Physical property

Answer 2

Information about matter that can be observed or measured without changing the matter’s identity.
Example: texture, color, volume, weight, height, Oder, magnetism, conductor of electricity, strength, flexibility, density.

Question 3

State of matter

Answer 3

Solid, liquid, gas

Question 4

Thermal conductivity

Answer 4

The rate at which a substance transfers heat. Plastic foam is a poor conductor.

Question 5

Solubility

Answer 5

The ability of a substance to dissolve in another substance. Flavored drink mix dissolves into water.

Question 6

Ductility

Answer 6

The ability to be pulled into a wire. Copper is often used to make wiring because it is ductile.

Question 7

Malleability

Answer 7

The ability of a substance to be rolled or pounded into thin sheets. Aluminum can be rolled into sheets to make foil.

Question 8

Inertia

Answer 8

The tendency of an object to resist a change in motion (a marbles inertia is to roll)
Mass is a measure of inertia. The more mass something has the harder it is to change its inertia. (A marble is easy to stop, it doesn’t have much mass, a boulder is hard to stop, it has a lot if mass)
