Physical Science I
Frank has a sample of steel that weighs 80 grams. If the density of his sample of steel is 8 g/cm3, this is the sample’s volume.
What is 10 g/cm3?
Its components are visible.
What is heterogenous mixture?
This unit is commonly used to measure density.
What is g/cm3?
This measures how tightly packed the atoms are in the substance.
What is density?
This separation method uses multiple layers of filtering substances and forces the liquid mixture through.
What is reverse osmosis?
It can be separated using distillation.
What is homogeneous mixture?
An alloy is made up of two kinds of metals. This alloy is uniform in appearance. It would be considered this.
What is in homogeneous mixture?
An electric iron is used to remove wrinkles from clothing. The electric iron is made of metal. The electric iron is an example of this property.
What is thermal conductivity?
This defines what iron is classified as.
What is an element?
This separation method requires a specific apparatus to capture the condensing liquid and it quite costly.
What is distillation?
Concrete is an example of this kind of mixture.
What is heterogenous mixture?
This many types of atoms are found in a compound.
What is at least 2?
A mixture that can be separated is called this.
What is a substance?
A substance that contains two types of atoms is called this.
What is a compound?
Donovan, a student of the month, bought a medicine to neutralize strong stomach acid. The medicine is most likely classified as which type of substance? A. an oil B. a base (alkaline) C. a metal D. a protein
What is B?
It may be mistaken for a pure substance.
What is homogenous mixture?
This describes the point in time when a solid begins to transition into a liquid.
What is melting point?
Daniel has a sample of pure copper. Its mass is 89.6 grams (g), and its volume is 10 cubic centimeters (cm3). The density of the sample is then....
What is 8.96 g/cm3?
Abigail and Isaac, April students of the month, are investigating the properties of the same unknown liquid. Abby pours a large sample of the liquid into a beaker, and Isaac pours a small amount of the liquid into a small cup. which property of the liquid is the same for both Abby's sample and Isaac's sample? A. volume B. mass C. density D. shape.
What is C?
Muddy water is an example of a mixture that can be separated using this.
What is a filter?
This substance contains only 1 type of atom.
What is an element?
Substances that do this can carry electrical current through the substance to complete a circuit.
What is conduct electricity?
Erica is working in the lab. She wants to remove the fine dust particles suspended in a sample of oil. This is the separation method she would most likely use.
What is filtration?
