What variables must be kept constant
There are potential variables that are kept constant for each trial in a set of trials.
The two types of variables are the CONSTANT and CONTROL.
Scientists change the independent variable but measure the dependent variable; other variables are kept constant.
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
In an experiment, variables that must be kept constant are called control variables. Two common examples include temperature and pH levels. These variables should be kept constant to ensure that any changes observed in the dependent variable are a result of the independent variable being tested.
What variables must be kept constant
All variables except one, the experimental variable, are kept constant in an experiment.
Variables that must be kept constant in an experiment are known as control variables. These variables are factors that can influence the outcome of the experiment, so keeping them constant ensures that any observed changes are due to the independent variable being tested.

Temperature & mass keep constant in Boyle's law. Volume and pressure are variable.
The two types of variables are the CONSTANT and CONTROL.
There are 'constant variables' , 'independant variables' and 'dependent variables' Constant Variable- things in the experimment that should be kept the same Independant variables- something that can be varied in an experiment Dependant variable- something that can be affected
In Boyle's law, pressure and volume are the two variables that change. The relationship between pressure and volume is inverse; as pressure increases, volume decreases, and vice versa, when the temperature is kept constant.

It is the constant of proportionality.
