What is Energy
Ability to do work
100
Describe Conduction
What is direct contact heat
100
What is kinetic energy
What is energy of motion
100
Identify the 3 states (phases) of matter.
Solid, liquid, gas
100
a rubber band is flying across the room is what type of energy
What is kinetic
200
if a ball is going up describe what is happening to the potential energy
What is increasing
200
Describe Radiation and Model
What is heat from a distance
200
Identify the seven forms of energy
What is (Mechanical) (Thermal/Heat) (Electrical) (Nuclear) (Light/Radiant) (Chemical) (Sound)
200
Explain the difference between the three states (phases) of matter using the MOLECULE MOVEMENT
(Solid - packed together/vibrate) (Liquid - loosely packed / flow) (Gas - not packed / very excited)
200
a stretched rubber band is what type of energy
What is potential
300
When doe a pendulum have only potential energy
What is when it is at the top of its swing
300
Model Convection and Describe all parts
What is hot air rising, cold air sinking
300
What are the two types of energy and what is the difference between them
Kinetic and Potential
300
What does adding energy (getting Warmer) do to molecules in matter?
Molescules speed up and spread apart- Causes to change states Solid to liquid Liquid to gas solid to gas
300
think about a guitar what are the energy chains that are occuring
What is mechanical to sound to heat
400
When does a pendulum have only kinetic energy
What is at the bottom of the swing when in motion
400
why does heat always travel from hot to cold, using molecules
What is hot molecules moving faster must bump into colder slower moving molecules which speeds up the slower molecules
400
What does the law of conservation of energy state
Energy can not be created or destroyed
400
What does removing energy ( getting cooler) do to molecules in matter?
Molecules slow down and come closer together which Causes matter to change state Gas to liquid liquid to solid gas to solid
400
why would you want to put your heater vents on the floor of a house and not the ceiling if trying to keep a house warm?
What is convection
500
Describe how a pendulum changes between potential and kinetic energy
What is starts in potential as goes down changes from potential to kinetic, then reaches fully kinetic before changing from kinetic to potential as it goes back up on the other side
500
Explain the difference between conduction, convection, and radiation. Give examples of each one.
Conduction, radiation, convection + examples
500
Explain the following phase changes: melting, evaporation, freezing, condensation, and sublimation.
Explain
500
Model how a solid molecule changes to a liquid, describe what is happening amount of energy and name the phase change.
What is very slow vibrating to flowing, melting, increase in energy
