Matter
Vocabulary
Vocabulary
The amount of matter in an object.
What is Mass?
The variable that you measure and that responds to change.
What is the Dependent Variable?
Matter that has a fixed volume, but NOT a fixed shape (example: pancake syrup)
What is a liquid?
The pure form of a substance that can't be separated into other substances.
What is an Element?
The formula for Density
What is D=M/V?
A physical property of matter that describes how closely packed the particles are. Hint: M/V
What is Density?
The variable in an experiment that the researcher manipulates or changes?
What is the Independent Variable?
Matter that has a fixed volume AND a fixed shape. (example: ice cube)
What is a solid?
The smallest part of an element that still retains its properties.
What is an atom?
The formula for mass.
What is M=DxV?
The amount of space that an object takes up.
What is volume?
The variables that you keep constant so that they don't affect the outcome of an experiment.
What is a control variable?
Matter that has neither a fixed volume nor a fixed shape (example: steam).
What is a gas?
A substance made up of two or more different elements that are chemically bonded together.
What is a compound?
The formula for Volume.
What is V= M/D?
The energy an object has because of its motion.
What is kinetic energy?
The first step of the scientific method that should be testable and not based on opinions.
What is "Asking a Question?"
Matter that conducts electricity, responds to magnetism, behaves like a gas and is the most plentiful in the universe.
What is a plasma?
A group of two or more atoms bonded together (can be the same or different elements).
What is a molecule?
The volume of an object that displaces water from 30 mL to 60 mL when using the displacement method.
What is 30 mL?
A characteristic of a substance that can be observed or measured without changing the identity of the substance.
What is a physical property?
This part of the scientific method should be a cause/effect statement, sometimes using an "If, then" format.
What is an hypothesis?
The law that states that matter cannot be created or destroyed in chemical reactions.
What is the Law of Conservation of Mass?
A combination of two or more substances that are physically blended together but not chemically bonded.
What is a mixture?
The density of a 45g block that displaces water in a cylinder from 45 mL to 60 mL. Don't forget units!
What is 3 g/mL?
