Temperature/Pressure
What are the particles doing in a pot of boiling water?
The particles will spread and get faster
Thermal Equilibrium.
When two objects are at the same temperature and no heat flows
Exothermic Reaction's system and surroundings:
System: cold
Surroundings: hot
Warm to cold
Tanning on the beach
Radiation
What are the particles doing in my ice cube tray?
Slow and close together
Define heat.
Endothermic system and surrounding temperature
System: hot
Surroundings: cold
cup of ice water
Hot air balloon
Convection
If I increase the pressure...
then the molecules will increase in speed and temperature and get closer together
Endothermic
Exothermic
My coffee cup in the morning
Coffee cup to the air molecules
A lamp shining in the room

How are the molecules behaving right above Alfredo's heating pad?
Fast and close together
Exothermic:
The release of heat energy
Making Ice is...
Exothermic
Conductors...
materials that transfer energy easily
metals, graphite
An attic feeling hot
Convection
What are the particles doing in my coffee after I put it in the freezer?
Close and slow
Temperature - Average Kinetic Energy
Thermal Energy - Potential and Kinetic Energy or TOTAL kinetic energy
Baking muffins...
Endothermic
Insulators
Do not allow energy to flow through them easily
Rubber, plastics, Styrofoam
