the amount of matter in an object
What is mass?
The equation to calculate density.
What is D=m/v?
The state of matter where particles move around fastest and have no defined shape or volume.
What is a gas?
Ice Melting
Physical Change
State the law of conservation of mass.
Mass cannot be created or destroyed.
A comparison of the amount of matter in an object to the amount of space it takes up.
What is density?
The density of a 700-gram rock with a volume of 350 cm3.
What is 2g/cm3?
The state of matter where particles flow freely but are confined to the shape of their container.
What are liquids?
Mixing sugar and water
Physical Change
How does temperature affect the rate of a chemical change?
Chemical changes will occur faster at higher temperatures.
The ability of a substance to dissolve in another substance
What is solubility?
The mass of a brick with a volume of 12 cm3 and a density of 3 g/cm3.
What is 36 grams?
The state of matter where particles are held in a defined position where they vibrate in place.
What is a solid?
Burning wood for a fire.
Chemical Change
Identify 3 signs of a chemical change.
Production of a Gas
Production of an Odor
Formation of a Precipitate (Solid)
Changes in Color
Changes in Energy
This physical property describes the ability for something to stretch or bend
What is ductility?
The volume of a liquid with mass of 32 grams and a density of 16 g/mL.
What is 2 mL?
True or False: Particles have more energy in a liquid than in a gas.
False. Particles of a gas will have more energy, which is why they move more freely.
Baking soda reacts with vinegar and forms a gas.
Chemical Changes
When Hydrogen and Oxygen combine they form water. How does the mass of the water compare to the mass of the Hydrogen and Oxygen separately?
They are equal.
Properties of matter that are determined by changing the substance.
Chemical properties
The density of a 24-gram cube with sides measuring 2 cm each.
What is 3 g/cm3?
How is the particle motion of a solid different from the motion of particles in a liquid or gas?
Particles in a solid do not move as freely.
A piece of apple rots on the ground
Chemical Change
What happened in the baking soda and vinegar balloon video to indicate that a physical change occurred?
Bubbling (change in energy), Production of gas.
