Answer:
The independent variable is what you change in the experiment.
Explanation:
The independent determines the dependent variable.
Answer:
Decantation
Explanation:
Decantation is one of the process of separating mixture containing solid and liquid. In this process, gravity plays a very important role. The solid part of the mixture is allowed to settle down. The liquid is removed and separated in another container. It is a process that helps in the purification of the liquid. The particles that are insoluble settles down and is further subject to be separated from the mixture.
Explanation:
The physical properties of matter tells us everything about the substance when no change is occurring to its constituents.
We observe such properties with our senses or instruments or some apparatus.
Examples are boiling point, melting point, density, viscosity, spectroscopic patterns, state of matter, odor, taste, hardness, texture etc
A chemical property is one that tells us what a substance can do with regards to whether or not the substance reacts with other substances.
Examples are flammability, rusting of iron, precipitation, decomposition of water etc.
