- Mass:
✔️ A measure that reflects the amount of matter.

✔️ A characteristic of matter that can be observed or measured without changing the sample's
composition. Example: density, color, taste, hardness, and melting point.
- Liquid:
✔️ A form of matter that flows, has constant volume, and takes the shape of its container.
- Homogeneous Mixture:
✔️ One that has a uniform composition throughout and always has a single phase; also called a
solution.
- Compound:
✔️ A chemical combination of two or more different elements; can be broken down into simpler
substances by chemical means and has properties different from those of its component elements.
- Liter:
✔️ The metric unit for volume equal to one cubic decimeter.
, - Celsius:
✔️ The metric unit of temperature measurement.
- Experimental Value:
✔️ The value measured in the lab.
- Chemistry:
✔️ The study of matter and the changes that it undergoes.
- Independent Variable:
✔️ In an experiment, the variable that the experimenter plans to change.
- Volume:
✔️ The amount of three-dimensional space occupied by an object.
- Chemical Property:
✔️ The ability or inability of a substance to combine with or change into one or more new substances.
- Gas:
✔️ A form of matter that flows to conform to the shape of its container, fills the container's entire
volume, and is easily compressed.
- Solution:
✔️ A uniform mixture that can contain solids, liquids, or gases; also called a homogeneous mixture.
- Conservation of Mass:
✔️ The principle stating that matter is not created or destroyed during a chemical reaction.
