Example A describes a chemical change and Example B describes a physical change.
Hey there!
In a scientific experiment, there are three types of variables: dependent, independent, and control.
Independent variables are the variables that are changed and doesn't depend on another.
Dependent variables are the variables that are depending on the independent variable. When the independent variable changes, it affects the dependent variable.
Control variables are the variables that are kept the same throughout the entire experiment. These don't change at all.
Hope this helps!

Answer:
False
Explanation:
Metals are materials that exist in the form of solid (state of matter). It is not true that solid solutions are only formed with metals. A solid solution is a <u>solid-state solution of one or more solutes in a solvent. </u>The solid solution can be formed with different forms. In general, solid solutions <u>formed by mixing a foreign elements Y (solute) with a perfect crystalline element X (solvent) </u>and atoms of both X and Y share the various crystal sites.
