Q

What is a high and low density?

A

A high density is when the particles of an object are close together and a low density is when the particles are more spaced out.

Q

What is diffusion?

A

The mixture of particles that occurs between fluids. For example, if I spray perfume in a room, the perfume particles mix with the air particles.

Q

What is convection?

A

The rise of a fluid caused by something heating it up, making it lighter and less dense.

17
Q

What are convection currents?

A

When hot fluids rise and cold fluids flow down to replace them.

18
Q

What is Brownian Motion?

A

The action of particles moving in random directions as the molecules vibrate by each other.

19
Q

What are insulators?

A

Something that reduces heat transfer by attracting less radiation. The opposite of conductors. Most non metals are insulators.

20
Q

What is radiation?

A

The travel of heat using electro-magnetic, infa-red waves, which need no particles to travel.

21
Q

What is a concentration gradient?

A

The diffusion of atoms at a high-low concentration gradient which is caused by random movements.
