What is matter?
Anything that has mass and takes up space

What process is matter going through when it goes from a liquid to a solid?
Freezing

What is the formula that we use to find the volume of an object?
Volume = length x width x height
200
Which form of energy is this? (Kinetic, potential, chemical, electromagnetic, or electrical) - the energy an object has because of its position Ex. A child sitting at the top of a slide waiting to go down
Potential energy

Do solids have: (A) a definite volume but no definite shape (B) a definite shape but no definite volume (C) both a definite shape and a definite volume (D)solids do not have a definite shape or a definite volume
Solids have (C) a definite shape and a definite volume
200
What are the 3 main states of matter?
Liquid, solid, and gas
200
What process is matter going through when it goes from a solid to a liquid?
Melting
200
What is the formula that we use in order to find the density of an object?
Density = mass/volume
300
Which form of energy is this? (Kinetic, potential, chemical, electromagnetic, or electrical) - the energy of electrically charged particles moving from one place to another. Ex. Power lines
Electrical energy
300
Do liquids have: (A) a definite volume but not a definite shape (B) a definite shape but not a definite volume (C) both a definite volume and a definite shape (D) liquids do not have a definite shape or a definite volume
Liquids have (A) a definite volume but not a definite shape
300
What is a physical property of matter?
A characteristic that we can observe without changing it into another substance.
300
What process is matter going through when it goes from a gas to a liquid?
Condensation

Find the volume for an object that has a length of 10cm, a width of 5cm, and a height of a 4cm.
200cm^3
400
Which form of energy is this? (Kinetic, potential, chemical, electromagnetic, or electrical) - a form of energy that travels through space as waves. Ex. An X-ray
Electromagnetic energy
400
Do gases have: (A) a definite volume but no definite shape (B) a definite shape but no definite volume (C) both a definite shape and a definite volume (D) gases do not have a definite shape or a definite volume
Gases (D) do not have a definite volume or a definite shape
400
What is a chemical property of matter?
A characteristic that describes it's ability to change into another substance.
400
What process is matter going through when it goes from a liquid to a gas? What are the two different ways it can do this?
Vaporization Boiling and evaporation
400
A square box has a volume of 200cm^3 and a mass of 150g. What is the density of the object? Remember to include the units.
.75g/cm^3
500
Which form of energy is this? (Kinetic, potential, chemical, electromagnetic, or electrical) - the internal energy stored in chemical bonds between atoms Ex. As wood burns around a campfire, the energy stored in the bonds of the molecules in the wood are released and produce light and heat.
Chemical energy
500
Weight and mass are both ways of measuring matter. What is the difference between weight and mass?
Weight can change based on location and mass does not. Your mass will always stay the same no matter where you are.
500
What is the difference between a chemical change of matter and a physical change of matter?
A chemical change produces one or more new substances and a physical change does not produce anything new.
500
What is the process where matter can go from a solid to a gas without going through the liquid phase of matter?
Sublimation
500
An object has a mass of 150 grams, a length of 15cm, a width of 10cm, and a height of 5cm. Find the volume and the density of the object. Will the object float or sink? Why?
Volume = 750cm^3 Density = .2g/cm^3 The object will float because the density of the object is less than the density of water which is 1g/cm^3.
