100
Heat transfer of energy that comes from the sun
What is Radiation?
100
Between the following elements, this one is a poor conductor of heat.
F - K - Fe - Ag
F - Fluorine?
100
a change in matter in which the substance that makes up the matter change into other substances.
chemical change
100
Identify the element from this Bohr model
Calcium
100
A chemical reaction where heat is absorbed and the surrounding temperature falls
What is endothermic?
200
The temperature at which an element or compound changes from solid to liquid.
Melting Point
200
Point where KE is highest and lowest
Kinetic Energy highest - Point X
Kinetic Energy lowest - Point W
200
the ability of a substance to be hammered or rolled into sheets.
malleability
200
Motion happening between 5:00 and 5:30
At rest
200
Type of wave behavior seen here.
What is refraction?
300
Mass per unit volume of an object as compared to pure water.
What is Density?
300
Of the following choices, these are signs of a chemical change:
-change in color, size and shape
-change in color, produces gas and heat
-change in states of matter (freezing, melting, boiling)
change in color, produces gas and heat
300
Motion that occurs after 30 seconds
Slowing down, decelerating, negative acceleration
300
a positively charged particle in the nucleus of an atom.
proton
300
Baking bread in an oven is an example of a chemical or physical reaction?
What is a chemical reaction?
400
Rust forms when iron is exposed to oxygen and moisture for a long period of time. Rust indicates this type of chemical reaction.
Chemical reaction
400
new substances formed in a chemical reaction
products
400
Which reaction can be reversed? Physical or Chemical
What is a Physical reaction?
400
Type of motion that this graph indicates
Constant motion (speed)
400
Number of protons, neutrons and electrons in Potassium
19 - protons
19 - electrons
20 - neutrons
500
This will happen to 2nd bulb if the 1st bulb goes out.
It will remain lit.
500
Point with highest and lowest potential energy
PE highest at W
PE lowest at X
500
This happens to particles as energy is removed.
Kinetic energy decreases and particles move closer together (volume decreases and density increases)
500
When heat moves from two things at different temperatures and must b
e touching
What is conduction?
500
a change in the size, shape, form, or state of matter that does not change the identity of the matter.
