Motion of Energy
Kinetic Energy
What are the 3 Phases of Matter?
Solid, Liquid, Gas
Why did the metal washers get warmer while the water got cooler? (Lab 1)
Energy from water > Washers
Atoms of washers move faster > Water molecules are slower
The temperature of washers increases as water temperature decreases
Gas to a liquid
Condensation
State with the fasteset movement
Gas
Average Kinetic Energy of atoms of molecules of a substance
Temperature
What is NaCl
Salt
What needs to happen to increase the rate of evaporation? (Lab 2)
Increase Energy
Ice changed to liquid
Melting
State which particles are closest together
Solid
Object/Material that easily moves heat
Conductor
When do ALL atoms stop moving?
Absolute Zero
What causes condensation to occur? (Lab 3)
Air reaches it's dew point
How does energy change from gas to liquid to solid?
Energy is lowering/decreasing
Gas particle arrangment
Farthest
Molecules of a solid speeding up overcoming attractions to move past one another
Melting
Water is made out of...
2 Hydrogens 1 Oxygen
What substance drops the freezing point of water? (Lab 4)
Salt
Changes in states that need increased energy
Melting and Evaporating
The arrangement of particles are socially distant
Liquid
Faster-moving molecules contact slower-moving molecules transferring energy
Conduction
What element is in EVERY living thing...
Carbon
When considering storing a frozen item what materials will increase or decrease the rate of melting?
Conductors and Insulators
Change of state when you go from the phase with the least amount of energy to the most amount of energy.
Sublimation
Distance between particles from greatest to least
Gas, Liquid, Solid
