Feel the Heat
Type of heat transfer that involves contact between two solids
Conduction
gasoline, fossil fuels and food are this form of energy
chemical potential energy
Which state of matter has the highest kinetic energy?
gas
the ability to do work
energy
Which atoms is a water molecule made of, and how many of each?
2 hydrogen atoms and 1 oxygen atom
Wind is an example of this type of heat transfer
Convection
energy stored in objects that can be stretched/twisted/bent is called _________________
elastic potential energy
What happens to the volume of matter when heat is removed?
Volume decreases
energy that is stored
potential energy
What is the photosynthesis input and output equation?
water + carbon dioxide + light --> sugar/glucose + oxygen
Why do dark solids get hotter than light solids when left out in the sun?
Because dark solids absorb radiant heat energy; light solids reflect it.
What form of energy is produce by friction?
thermal energy
In order for matter to change state from liquid to gas, or solid to liquid, ___________ needs to be added.
heat/thermal energy
Energy of motion is called ____________ _________
kinetic energy
Electricity is caused by the flow of __________________ through a conductor.
Hint: these are a type of subatomic particle!
electrons
Infrared waves are a type of __________________ radiation.
electromagnetic
What are the three output energies of the sun?
Thermal, light, sound
Volume increases when heat is added because the increase in thermal energy helps break ______________________________ between particles, therefore allowing them to spread out
bonds/forces of attraction
Energy cannot be ___________ or ____________
created or destroyed
How long does it take light to reach the earth from the sun?
8 minutes and 20 seconds
acceptable answer: between 8 and 9 minutes
Heat-sensitive thermal imaging cameras use what type of waves to measure body temperature distribution?
infrared
Hydrogen bombs are extremely dangerous as a result of what reaction that occurs between the hydrogen particles?
Nuclear fusion
Why do gas particles eventually condense, and become liquid again?
Because they eventually lose heat/their thermal energy decreases, causing them to slow down and move closer to each other.
the average kinetic energy of an object is its ____________________
temperature
As a group, act out condensation and freezing. Then suddenly sublimate. YOU ARE THE PARTICLES.
(you have one minute to prepare)
