Matter
Anything that has mass and takes up space.
Physical State
The classification of matter as a solid, liquid, or gas.
Thermal Energy
Energy that can be measured by a thermometer.
Boiling Point
The temp. at which a substance changes states from a liquid to a gas.
100 degrees Celsius
Substance
A single part of a mixture or solution.
Physical Properties
Measurable characteristics that describe the physical state of something
Relative Density
How dense something is compared with a reference material.
Conductor
Material that allows heat or electrical energy to easily flow through it.
Condensation
Physical change in matter from a gas to a liquid.
Solute
The substance being dissolved.
Mass
The amount of matter in something.
Solubility
Measurement of the ability of a solid to dissolve in a liquid.
Insulator
Material through which heat or electricity does not easily flow.
Evaporation
Physical change in matter from a liquid to a gas.
Mixture
A combination of two or more substances where each keeps its own properties and can be easily separated.
Volume
How much space something takes up.
Dissolve
Spread out uniformly in a liquid.
Heating
Rising in temp.
Melting Point
The temp. at which a substance changes states from a solid to a liquid.
zero degrees Celsius
Heterogeneous Mixture
You can see all of the components.
Weight
How heavy or light something is.
My particles are tightly packed.
I have a fixed shape.
Solid
Cooling
Lowering in temp.
Freezing point
The temp. at which a substance changes states from a liquid to a solid.
zero degrees Celsius
Solution
A particular type of mixture where a substance dissolves in another; the molecules spread evenly through the other substance, it makes a new substance that looks like one.
Magnetism
The property of attraction to a magnet.
I fill the shape of a container.
Liquid
Temperature
How hot or cold something is.
Thermometer
Tool used to measure how hot or cold something is.
Solvent
The substance doing the dissolving; the liquid.
Pick an item and describe its physical properties.
desk: brown and black
solid, hard, smooth, cold, 2.5 feet tall
My particles are randomly moving everywhere.
I fill the shape of a container.
You can not see me.
Name 3 insulators and 3 conductors
insulators: not made of metal
conductors: made of metal
If my thermometer says 58 degrees celsius, how many more degrees until my liquid hit boiling point.
42 degrees celsius
Homogeneous Mixture
You cannot see all the components easily; it looks like one but can still be separated.
