States of Matter Flashcards
The invisible mixture of odorless, tasteless gases that surrounds the Earth
Air
A tool used to find the mass of an object
Balance
To observe the similarities or likenesses between objects
Compare
The process where a substance that is a gas changes into a liquid
Condensation
To observe the differences between objects
Contrast
Describes the ability of a solid to keep its own shape unless acted on by a force
Definite shape
The process of changing a liquid to a gas through heating or the motion of air. It doesn’t necessarily involve bringing the liquid to the boiling point.
Evaporation
The temperature at which a substance turns from a liquid to a solid
Freezing point
A tool, usually shaped like a hollow cone with a tube extending from the point. Can be used to catch and direct the downward flow of a substance.
Funnel
A state of matter that has mass and volume but has no definite shape and does not take up a definite amount of space. It takes the space and shape of its container
Gas
A tool used to measure the volume of matter
Graduated cylinder
A metric unit of measurement used for determining the mass of an object (1 of 2)
Gram
A metric unit of measurement used for determining the mass of an object (2 of 2)
Kilogram
State of matter that takes up a definite amount of space (volume) and no definite shape. Takes on the shape of the container, can flow, and cam be poured from one container to another
Liquid
A metric unit for measuring the volume of liquids.
Liter (L)
1 Liter = ____ milliliters
1000
The amount of matter (stuff) within a substance or an object. The tool used to measure this is the balance and the units of measure are milligrams and grams.
Mass
Anything that has mass and takes up space (volume)
Matter
The temperature at which a substance turns from a solid to a liquid
Melting point
A metric unit for measuring volume
Milliliter (ml)
1000 millileters = ____ Liter
1
A combination of two or more materials that can be separated
Mixture
A metric unit used for measuring force. Weight is the measure of the force of gravity, so it can be measured in this unit.
Newton
A change in the stat of matter. Occurs when a material changes from a solid to a liquid or gas, liquid to a gas or solid, or gas to a solid or liquid.
Phase change
Characteristics by which matter is described. Hardness, size, color, shape, flexibility, buoyancy (sinking and floating), state of matter (solid, liquid, gas), odor, mass, and volume.
Physical characteristics
Uses the heat from the sun to evaporate water. Can be used to change unclean water or salty water into fresh water
Solar still
State of matter in which matter has a definite shape and volume
Solid
Tool used to find the weight of an object
Spring scale
Describes whether a substance is a solid, liquid, or gas
State of matter
Amount of space taken up by a substance or an object, regardless of its shape or state.
Volume
The force of gravity acting on an object. Not the same as mass.
Weight
