CCR
What does CCR stand for?
Conduction, Convection, Radiation
What is potential energy?
Stored energy
What is kinetic energy?
Energy of motion
This type of heat transfer doesn't need matter in order to occur.
Radation
The average kinetic energy of particles.
Temperature
Which has more CPE, regular or diet soda & why?
Regular, it has calories which are units of energy
What is heat transfer in the form of waves?
Radiation
If a diver dives off a cliff towards the water, where is the divers KE the greatest?
Right before hitting the water
KE depends on what two factors?
Mass & speed (velocity)
What are two examples of convection currents?
Boiling water
Air in your house
Lake turnover
The winds around Earth
The unit used to measure energy.
Joules
Who is the voice of the Mufasa in The Lion King?
James Earl Jones
Which method of heat transfer doesn't work in solids?
Convection
What word is used to describe energy changing forms?
Tranformed
What is the equation for calculating GPE?
GPE = m x g x h
Briefly describe how conduction works.
Two object are in contact with each other and KE is transferred
Energy can not be created or destroyed. It can be transferred or transformed.
What are 3 units that temperature can be measured in?
Fahrenheit, Celsius, Kelvin
What type of heat transfer works best in solids?
Conduction
What factors affect the gravitational potential energy of something?
Mass & height
Between the bonds of atoms
What do all objects give off that we are able to see with thermal cameras & night vision goggles?
Infrared Radiation
What is the equation to calculate kinetic energy?
KE = 1/2 x m x v2
Why does a large cup of cold coffee have more thermal energy than a small hot shot of espresso?
There is more matter (which means more KE total)
Lake turnover is an example of this type of heat transfer.
Convection
What is thermal energy?
Total KE from movement of atoms
If you break down the unit of a Joule, what is it equal to?
kg x m2/s2
Explain why this saying makes sense, "In science, there is no definition for the word cold."
Cold is just slower movement, there is still thermal energy.
What does absolute zero mean? (give me the temp and what is happening to particles)
0 degrees Kelvin, absolutely no movement of particles
When you stretch a rubber band, it has this type of energy stored.
Elastic Potential Energy
