The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
Variable
A constant in an experiment is something that does not change, such as the temperature, pressure, or a control variable that is kept the same throughout the experiment to ensure accurate results.
A variable.
There are different types of factors that can change in an experiment. The environmental factors may change, and are out of your control. The variables in the experiment may also be changed but, are usually controlled by the individual conducting the experiment the majority of the time.
A control is the standard to which an outcome of an experiment is compared, but a variable is something in an experiment that can change.
A scientific experiment must be done by something that can show change. All of these can be variables.
an independent variable
Something that dose not change in an experiment, that the results are compared too.
You would do that to observe the result of changing it.
a dependent variable is something that you cannot change but comes out as a result/an independent variable is something that you change in your experiment like the temperature of something or the amount of something
a dependent variable is something that you cannot change but comes out as a result/an independent variable is something that you change in your experiment like the temperature of something or the amount of something
A variable represents things that are involved in an experiment. The control is the variable that doesn't change regardless of the experiment.
