States Of Matter

Question 1

Solid

Answer 1

Definite shape, definite volume. The particles are tightly packed and arranged in a specific pattern. The particles cannot move past one another.

Question 2

Liquid

Answer 2

Indefinite shape, definite volume. The particles are still tightly packed but can rotate and slide past one another.

Question 3

Gas

Answer 3

Indefinite shape, indefinite volume. The particles are spread out and have very little attraction to one another. The particles move randomly.

Question 4

What happens solids, liquids and gases when they are heated?

Answer 4

They all expand

Question 5

Warmer gases and liquids are _______ and will _________

Answer 5

Warmer gases and liquids are less dense and will rise.

Question 6

Cooler gases and liquids will ____.

Answer 6

Cooler gases and liquids will sink.

Question 7

Melting / Freezing

Answer 7

The process of converting solid to liquid or liquid to solid. This happens at the freezing / melting point of a substance (for water this is 0C or 32F). The temperature substance will not change during the process or melting or freezing.

Question 8

Vaporization / Condensation

Answer 8

The process of converting liquids to gas or gas to liquid. Thugs happens at the boiling point of a substance (for water this 100C or 212F). The temperature of the substance will not change during this process.

Question 9

Sublimation / Deposition

Answer 9

The process of transitioning directly from as solid to gas or gas to a solid. An example of sublimation is dry ice at room temperature, an example of devotion is frost.

Question 10

Two types of vaporization

Answer 10

Evaporation and boiling

Question 11

Evaporation

Answer 11

Happens from the surface of a liquid

Question 12

Boiling

Answer 12

Happens throughout a liquid

Question 13

Convection

Answer 13

The transfer of heat by the movement of particles within a substance. Convection can only occur in gases and liquids, it can not occur in solids because the particles in solids are not free to move.

Question 14

Conduction

Answer 14

The transfer of heat by direct contact or collisions between two objects or particles

Question 15

Radiation

Answer 15

The transfer of energy by electromagnetic waves. This type of energy trader can pas through solids, liquids, gasses and vacuums like space. Types of electromagnetic waves include visible light, radio waves, microwaves, infrared, ultraviolet, e-rays and gamma rays.

Question 16

Insulator

Answer 16

A material which does not allow heat to pass through ti easily. Plastic, styrofoam, animals’ blubber and fur are good examples of insulators.
