What is when a material is heated, the particles expand?
100
When you measure the average kinetic energy of a particle, you're finding this.
What is temperature?
100
Energy is the ability to do this.
What is cause change?
100
Water waves and sound waves do this.
What is transfer energy?
100
These can easily flow and change places.
What are fluids?
200
For conduction to occur the two materials must be this.
What is in contact with eachother?
200
This will increase whenever temperature increases.
What is the volume of the object - like thermal expansion of a bridge?
200
A spring can store energy when it is these two things.
What is compressed and stretched?
200
Holding your book isn't, but pushing it is.
What is work?
200
Air, plastic foam, fiberglass, cork, and wood.
What are insulators?
300
Convection currents cause this to rise and this to sink.
What is hot air will rise, and cold air will sink?
300
The coldest temperature possible.
What is 0 Degrees Kelvin?
300
This always moves from warmer objects to cooler objects.
What is thermal energy?
300
3 Electromagnetic Waves.
What are light waves, radio waves, microwaves, infrared rays, and X-rays?
300
You have a lot of this when sitting on the couch.
What is potential energy?
400
This process can transfer thermal energy through a vacuum - and not the Hoover kind.
What is radiation - like the sun's rays?
400
When thermal energy stops moving.
What is when both the objects are the same temperature?
400
How we measure energy.
What is the unit Joules?
400
When you light a marshmellow on fire, you're converting this to this.
What is chemical potential energy to thermal energy & radiant energy?
400
Collision of particles?
What is conduction?
500
An example of each.
What is:
Conduction - Metal rod in fire?
Convection - Hot air balloon rising?
Radiation - Sun's rays hitting Earth?
500
The two places that the Farenheit scale is used.
What is the United States and Canada?
500
Increase the Mass. Increase the heigh above the ground.
What is increase the gravitational potential energy?
500
3 Energy Conversions - be specific.
What are:
Kinetic energy to potential energy (riding a bike and stopping at the top of the hill)
Chemical to Kinetic (eating food that gives you energy)
Chemical to Thermal/Radiant (burning a piece of wood)
500
Without this transfer of energy, we'd all be dead.
