1 The phenomenon that thermal energy transfers from one molecule to the one next to it due to the temperature gradient is called conduction.
The movement of molecules within liquids or gases is convection.
Radiation is a process that energetic particles or waves travel through a medium or space.
2 Sublimation is the change from solid to gas.
Deposition is the change from gas to solid.
Evaporation is the change from liquid to gas.
Condensation is the change from gas to liquid.
Melting is the change from solid to liquid.
Freezing is the change from liquid to solid.
4 200°F=93.33°C
200K=-73.15°C
so the answer is 200°C 200°F 200K
5 The molecules in the half full one move faster because the molecules has less room.
The full glass requires more heat to raise its temperature by one degree Celsius.
