A control is a duplicate setup of the experiment you are performing with everything identical except for the variable that you are testing.
Or, it is how the experiment would happen naturally, without you doing anything.
For example, if you are testing the effects of a certain medication on humans, you give half of the subjects the medication and the other half a placebo, which is a sugar pill that has no effect. The latter group is the "control group". Their purpose is to remove the psychological effect of taking the medication from the results of the experiment, so that the only variable remaining is the actual effects of the medication.
Constants are things that are kept the same for all trials, like making sure that every subject is taking a pill (and that they believe it is the medication in question, ever if it is only a placebo)

What is the difference between the equilibrium constant Kf and the solubility product constant Ksp in a chemical reaction?
The equilibrium constant Kf measures the extent of a reaction at equilibrium, while the solubility product constant Ksp measures the extent of a substance dissolving in a solution.
What are difference between constant immersion hydrometer and constant weight hydrometers?
Constant immersion hydrometers are designed to be fully submerged in the liquid being tested, providing readings based on the buoyancy principle. Constant weight hydrometers are initially weighed in air and then in the liquid, with the difference in weight determining the liquid density. Constant immersion hydrometers are typically more accurate for measuring specific gravity, while constant weight hydrometers can be more convenient for quick measurements.
Is the spacing between the lines in the spectrum of an element constant or does it vary?
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.
What is the difference between positive and negative control in an experiment?
In an experiment, a positive control is used to show that the experiment can detect a specific response, while a negative control is used to show that the experiment does not detect a response when it should not.
How can one determine the equilibrium constant Kp from the equilibrium constant Kc?
To determine the equilibrium constant Kp from the equilibrium constant Kc, you can use the ideal gas law equation. The relationship between Kp and Kc is given by the equation Kp Kc(RT)(n), where R is the gas constant, T is the temperature in Kelvin, and n is the difference in the number of moles of gaseous products and reactants. By using this equation, you can calculate the equilibrium constant Kp from the given equilibrium constant Kc.
What is the difference between constants and control?
A control receives no Independent Variable (or IV) and a constant stays the same throughout an experiement.
Difference between rate constant and specific rate constant?
There is no difference between them they are same rate constant is another name of specific rate constant
What is the difference between variable constant and control?
A constant is always fixed and won't change in an experiment. The control is the standard that you are testing against to see how experiment outcomes change when the testing factors are altered.
What the difference between a variable and control?
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
What is the difference between a constant in a graph and a constant in a experiment?
the difference between a constant in a graph and a constant in a experiment is that when on a graph, the constant is the thing that changes, and in a experiment it is the part that stays the same.
What is the difference between a control variable and a control treatment?
A control variable is a factor that is held constant in an experiment to prevent it from influencing the outcome. A control treatment, on the other hand, is a specific group or condition in an experiment that receives no experimental manipulation and is used as a baseline for comparison with the treatment groups.
What is the difference between feedback and control?
difference between feedback and control
What is the difference between ordinary prism and constant deviation prism?
difference between ordinary prism and constant deviation prism
Difference between attenuation constant and phase constant?
nothing
What is the difference between an experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between an experimentation variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
