Mass, Volume, Density
Describe what mass is in your own words
The amount of matter or stuff in something
The three phases of matter:
Solid, liquid, gas
Molecules:
A group of atoms
An energy transfer is:
When energy is taken from one thing and given to another thing
Volume is:
The amount of space that something occupies
The phase of matter that has minimal vibrations and movement
Solid
Chemical reaction
A process that involves rearrangement of the molecular structure of a substance
Foil is a good conductor because:
It's made of aluminum, which is a metal that has lots of space between the atoms to hold lots of energy
Weight and mass are different because:
Weight measures a force and mass is how much something weighs
When water is cooled the molecules of water move _______
When water is warmed the molecules move ________
Slower
Faster
Displacement
The object pushes out a volume of water that is equal to its own volume.
Wood and plastic is not a very good conductor of heat because:
Neither can hold heat very well or for very long
The displaced volume of a chunk of steel is 92ml with an initial volume of 50ml, so the volume of the steel is:
V = 92ml - 50ml = 42ml
The phase of matter where the atoms are spread far apart, with high levels of energy
Gas
Evaporation
The process in which a liquid is heated to release water vapor (a gas)
Metal is a good conductor of heat or electricity because:
350g / 200cm3 = 1.75g/cm3
The type of energy that is transferred into a liquid when heated on a stove or hotplate
Thermal energy
The Scientific Method
The method or procedure of scientists that has an ordered set of directions to complete an experiment
A conductor of heat is:
Something that allows heat to be trapped or released very slowly
