Word/ Fact | Definition/ Fact |
Chemistry | The branch of science that deals with the properties of matter. |
Matter | Anything that has mass & takes up space |
Mass | The amount of matter in an object or body- measured in grams |
Weight | The amount that gravity pulls on a certain mass- measured in pounds |
Solid | Has it's own shape, but can change |
Fact for weight | Weight depends on mass, but mass doesn't depend on weight |
Fact for solid | A solids atoms are packed too tight to let them move |
Liquid | Takes the shape of it's container |
Fact for liquid | A liquids atoms are packed loosely, but not too loosely |
Gas | Only takes the shape of it's container if trapped |
Fact for gas | The atoms move freely in gas |
Volume | The amount of space an object takes up- measured in cubic centimeters or liters, meters,etc... |
Water Displacement | A method of measuring volume of an irregularly shaped solid |
Directions For Water Displacement | Fill a measuring cup with a set amount of water. Then, place the object in the water.Measure the difference before & after |
Buoyancy | The weight of an object sinks until it's weight is displaced in water |
Fact | Hollow things float |
Fact | Buoyancy can also be in air.Like hot air balloons,Hot air moves faster than cold.If you have enough air in an object, it goes up |
Density | A measure of how tightly packed the atoms of a substance are- measured by mass divided by volume |
Fact | The density of water is 1 |
