What is matter?
Anything that has mass and takes up space
Explain the motion and distance of particles in a gas.
The particles are moving very quickly and they are far apart from each other.
What is the formula for density?
Density equals mass divided by volume.
Give an example of a physical property
Color, texture, taste, odor, malleability, ductility, magnetic ability (anything that you can observe or measure without changing the properties of a substance)
True or false: The particles in all objects, whether solid, liquid, or gas, are moving.
True
What force impacts the weight of an object?
Gravity
How are thermal energy and kinetic energy related to each other?
As thermal energy increases, kinetic energy increases. As thermal energy decreases, kinetic energy decreases.
How do you calculate the volume of an object using displacement?
1. Find the initial volume of water in the graduated cylinder.
2. Place the object in the graduate cylinder and measure the volume again.
3. Subtract the volume of the graduated cylinder with the object and the volume of the graduate cylinder without the object.
Give an example of a chemical property
Flammability, reaction with vinegar, rusting, tarnishing
Physical or chemical change: The muffler of a car rusting
Chemical
How do you calculate the volume of a rectangular prism?
Multiply the length, width, and height
Evaporation
The mass of a sample of maple syrup is 5.586 g. The volume of the sample is 4.2 mL. What is the density of the maple syrup?
1.33 g / mL
Physical or chemical change: Taking a bite out of an apple
Physical
The mass of a sample of honey is 12.096 g. The volume of the honey is 8.4 mL. What is the density of honey?
1.44 g / mL
List one change of state and list the starting state of matter and the ending state of matter.
Melting - Solid to liquid
Freezing - Liquid to solid
Vaporization - Liquid to gas
Condensation - Gas to liquid
Sublimation - Solid to gas
Deposition - Gas to solid
What are the three changes in state where thermal energy is increased?
Sublimation, melting, evaporation
4 mL
Physical or chemical change: Lighting a match
Chemical
Explain how the kinetic energy and thermal energy of molecules changes during evaporation.
The kinetic energy increases and the thermal energy increases.
What is an example of a situation when someone's weight would change but their mass would remain the same?
Going into outer space
1. What two states of matter are involved in deposition?
2. How does the kinetic energy of the particles change during deposition?
3. How does thermal energy change during deposition?
1. Gas and solid
2. Decreases
3. Decreases (it is lost)
1.6 mL
Physical or chemical change: Ice cream melting
Physical
What is an example of deposition?
Frost on a window or car windshield
