Do molecules generally move faster at 45 C or 106 C?
45 C because molecules have more energy than in 106C
106 C because molecules have more energy than in 45C
106 C because molecules have less energy than in 45C
45C because molecules have less energy than in 106 C
When you place the metal in boiling water, heat flows from the _________ to the _______.

The transfer of thermal energy as electromagnetic waves
Convection
The transfer of thermal energy through liquids and gases
The transfer of thermal energy through solids
The transfer of thermal energy as electromagnetic waves
Radiation
The transfer of thermal energy as electromagnetic waves or particles
The transfer of thermal energy through solids

Conductor
A material that allows heat to flow through it easily
A material that energy does NOT transfer through easily
Energy that travels in the form of electromagnetic waves
Insulator
A material that slows the heat transfer through it
A material that thermal energy travels through easily
The measure of the kinetic energy of an object’s molecules
2nd law of thermodynamics
Every time energy changes form, some of it is lost to the environment
Energy can't be created or destroyed
All energy generates heat
The 1st law of Thermodynamics
Energy can not be created or destroyed. It just changes forms.
Energy can only be created by the sun
Some energy is lost to the environment.
When you place the metal in boiling water, heat flows from the _________ to the _______.
metal to the boiling water
bottom of the metal to the top half of the metal
bottom of the water to the top of the water
boiling water to the metal
Match the law of thermodynamics with its definition.
0th Law of Thermodynamics
Objects in contact will eventually reach thermal equilibrium.
1st Law of Thermodynamics
Energy lost by a system is equal to the energy gained by its surroundings.
2nd Law of Thermodynamics
Entropy of a system increases.
3rd Law of Thermodynamics
A system's entropy approaches a constant value as its temperature approaches absolute zero.
