Definitions
A change in state or form without a chemical reaction taking place.
Physical Change
The substance changes from a solid to a liquid.
Melting
Any characteristic of a substance that can be observed without changing the substance
Physical Property
What is the formula for density?
Density = mass / volume
A new substance is formed through a chemical reaction.
Chemical Change
The substance changes from a gas to a liquid.
Condensation
Any characteristic of a substance that may be observed when it undergoes a chemical change
Chemical Property
An object has a mass of 570 g and a volume of 2280 cm^3. Calculate its density.
0.25 g/cm^3
A neutral group of two or more atoms held together by covalent bonds.
Molecule
The substance changes from a solid to a gas
Sublimation
Breaking glass is an example of.
Physical Change
A cat has a volume of 0.004 m^3 and a density of 980 g/m^3. Calculate the mass of the cat.
3.92 g
A substance made of two or more elements chemically combined in a specific ratio or proportion.
Compound
The substance changes from a gas to a solid, without first becoming a liquid.
Deposition
Rusting is an example of.
Chemical Change
A bottle of water has a density of 1000 g/mL and a mass of 0.5 g. Calculate the volume of the water bottle.
0.0005 mL
The measurement of how much mass of a substance is contained in a given volume.
Density
Water boiling is an example of.
Vaporization
Smell is an example of.
Physical Property
A cube with a side length of 7 cm, has a density of 10,800 g/cm^3. Work out the mass of the cube.
7×7×7=343 cm^33
343×10,800 = 3,704,400, g
