What is the total kinetic and potential energy in an object called?

THERMAL ENERGY

100
Rapid evaporation that takes place within a liquid as well as at its surface is called...
BOILING
200
What is the role of "loose" electrons in heat conductors like metals...
They carry energy from one part of the conductor to another.
200
Objects that are good at absorbing radiation are usually also good at...
Emitting Radiation.
200

The metric SI unit of measurement for temperature

CELSIUS

200

What is the measure of the average kinetic energy of the molecules of an object?

TEMPERATURE

200
The change of phase from liquid to solid is called....
FREEZING
300
Distinguish between a conductor and an insulator.
A conductor readily conducts thermal energy; an insulator inhibits flow of thermal energy.
300
Distinguish the difference between evaporation and boiling.
-Evaporation is change of phase at a liquid's surface -Boiling is change of phase throughout the liquid
300
Do the molecules in a liquid all have about the same speed or is there a wide variety of speeds? Give one example with your answer.
There is a wide variety of speeds.
300
Name the four phases of matter...
Solid, Liquid, Gas, Plasma
300
The change of phase from solid to liquid is called...
MELTING
400
In what sense do we say there is no such thing as cold?
Cold isn't a thing in itself, but is an absence of thermal energy or heat.
400
What is a good conductor that readily gives up its electrons when heated?
METALS
400
Why is boiling and evaporation a cooling process?
Because faster-moving (more energy and heat filled) molecules of liquid evaporate taking that heat and energy with them.
400
When molecules jump directly from a solid to a gaseous state this is known as...
SUBLIMATION
400
The change of phase from gaseous to liquid is called...
CONDENSATION
500
Which normally cools faster, a black pot or silver pot of hot water? Why.
A good absorber heat is also a good emitter heat, therefore the black pot would cool faster.
500

Determine which has more thermal energy; a full cup of tea at 25 degrees Celsius or a full pot of tea at 25 degrees Celsius AND explain why.

The pot of tea would have more thermal energy since TE is a measure of both kinetic and potential energy whereas Temperature is just a measure of the kinetic energy.  Although they both have the same kinetic energy (Temp), the pot has more mass so it has more potential energy giving it more thermal energy

500

When temperatures between 2 or more substances balance out, heat stops flowing, then the system (or set of systems) is said to be in what?

THERMAL EQUILIBRIUM

500
Energy being absorbed, energy being removed, and heat transfer are all parts of this type of change
