This type of property depends on the amount of matter present
What is an extensive property?
This testable explanation is created before an experiment.
What is a hypothesis?
This state has a definite shape and definite volume.
What is a solid?
This pure substance contains only one type of atom.
What is an element?
This prefix represents 10^3.
What is a kilo?
Mass is this type of property.
What is an extensive property?
This is the variable intentionally changed by the scientist.
What is the independent variable?
This state has a definite volume but takes the shape of its container.
What is a liquid?
Saltwater belongs to this class of matter.
What is a homogeneous mixture?
This prefix represents 10^−3.
What is milli?
This property remains the same when a sample is cut in half.
What is density?
This is the variable measured during an experiment.
What is the dependent variable?
This change occurs when a gas becomes a liquid.
What is condensation?
Vegetable soup belongs to this class of matter.
What is a heterogeneous mixture?
One of these equals 10^−9 meters.
What is a nanometer?
Density and boiling point belong to this category of properties.
What are intensive properties?
This group provides a standard for comparison.
What is the control group?
This process changes a gas directly into a solid.
What is deposition?
This pure substance contains two or more elements chemically bonded together.
What is a compound?
This prefix represents 10^−12.
What is pico?
A 40-g sample has a volume of 10 mL. When it is divided in half, this intensive property remains 4 g/mL.
What is density?
After experimental results do not support a hypothesis, a scientist should take this next step.
What is revise the hypothesis and test it again?
The particles in this state have enough energy to spread out and completely fill their container.
What is a gas?
Unlike mixtures, compounds can only be separated into their elements through this type of change.
What is a chemical change?
A bacterium is 2×10−6 meters long. Express its length using the appropriate SI prefix.
What is 2 micrometers?
