What effect does heating a particle in one part of a substance have on the nearby particles?
The heated particles transfer radiation to the nearby particles.
The heated particles collide with nearby particles, causing them to vibrate more as well.
The heated particles stay still
Which of these is a measure of how hot or cold something is?
temperature
radiation
insulation
friction
What is an insulator?
a material that heat moves through easily
a material that heat does not move through easily
a material that turns cold when heated
a tool for measuring temperature
What is a conductor?
a material that heat moves through easily
a material that heat does not move through easily
a material that turns cold when heated
a tool for measuring temperature
What do heated particles need to do to transfer energy by conduction to nearby particles?
Vibrate
Collides
Which state of matter does conduction occur in most easily?
Gas
Liquid
Vacuum
Solid
Why is conduction very slow in liquids?
There are no particles in liquids, so there aren't any collisions.
The particles are loosely packed, so they don't collide often.
The particles are closely packed, so they collide often.
Why does conduction rarely happen in gases?
There are no particles in gases, so there aren't any collisions.
The particles are closely packed, so they collide often.
The particles are spread out, so the particles rarely collide.
Why does not conduction occur in a vacuum?
There are no particles in a vacuum.
Energy can't be transferred through a vacuum.
Which of the following substances are considered to be thermal insulators?
gases
liquids
metal-solids
non-metal solids
Think about a pan of water sitting on an electric stove. The stove is then turned on to high.
What will happen to the movement of the particles in the pan?
They will slow down
They will stay the same speed
They will stop moving
They will speed up
Freddie is drinking a cold glass of Kool-Aid in the sun on a hot day. He puts the glass down in the sun and the glass begins to warm.
What is happening to the small particles that make up Kool Aid? They. . .
contract
slow down
move faster
disappear
