Thermal Energy VS Tempersture

Question 1

What is the particle arrangement in solids?

Answer 1

Tightly packed in an ordered pattern. Only little movement.

Question 2

What is the particle arrangement in liquids?

Answer 2

Particles are quite close together and move with random motion throughout the container.

Question 3

What is the particle arrangement in gases?

Answer 3

Widely spaced out and move rapidly in random directions.

Question 4

How can a substance go from one state of matter to another state of matter?

Answer 4

By adding or removing energy (heating or cooling).

Question 5

What is kinetic energy? Which state of matter has the most kinetic energy and which has the least?

Answer 5

Kinetic Energy is the energy of movement. Gas has the most KE and liquid has the least KE.

Question 6

What is the term used for the average kinetic energy of particles in matter? What units is this measured in?

Answer 6

Temperature. Measured in degrees celsius.

Question 7

What is the particle model?

Answer 7

All matter consists of many, very small particles which are in a continual state of motion. Particles move further apart when heated.

Question 8

What is temperature?

Answer 8

The measure of how hot or cold an object is. Temperature is measured in degrees celsius.

Question 9

What is heat?

Answer 9

The name for the type of Kinetic Energy possessed by particles. Heat is measured in Joules.
