all but 1...the 1 yu want tu test.
These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.
In case of BOYLE'S law,temperature is held constant! thank you!!
In Charles' Law, the mass is held constant which means that the pressure on the gas is constant.
The gauze bandage was held tightly so as to keep constant pressure on the wound.
A control variable is a variable that is held constant in a research analysis.
When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.
Constants are factors in an experiment that stay the same. This should not be confused with controls -- which is a standard used for comparison

-conditions or events that could affect the dependent variable (outcome of an experiment) but do not, because they are held constant for for both the experimental and control group.

Constant means strait line and variable is an arch which is not a strait line

Scientists perform controlled experiments in order to reduce as many third variables as possible. This means they are trying to prevent variables not directly related to the study from influencing the results.
The control is the variable that is held is held constant throughout all experiments, and duplications of them. By isolating control variables sources of error and or influence on a system can be managed and understood.
