A control variable is one that is set for the entire duration of the experiment. When measuring the Heat capacity of a gas (for instance) you can have Heat Capacity at constant volume or Heat Capacity at constant pressure Cv and Cp. In these cases the control variable would be Volume in the first case and Pressure in the second.
A controlled variable is one that you can vary in a controlled way. In the measurement of an Ideal gas PV=nRT you have to be able to vary one of the P,V, n, or T to get meaningful readings at all. So, depending on how your experiment is set up, the ones that are the controlled variables are the ones you make measurements of and the other that is not allowed to vary is the control variables.
P=(V/n)(R)T P and T are controlled, V and n are control.
(PV) = nT(R) n and T are controlled, P and V are control
P(V) = n (RT) P and n are controlled, V and T are control
(R is a constant and doesn't vary outside of measuring systems)
there are seven variation of possible experiments with an ideal gas, somebody else can finish this for me if they they think they are as clever as I am.
What else can I help you with?
What is the difference between control and controlled variable?
control is when nothing is done to the experiment and controlled variable is that you have control over 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 a conrtol group and an experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is a factor in a experiment that you measure to gather results?
It is a variable. The independent (manipulated) variable is the factor that is different between the control and experimental groups. The dependent variable is the difference resulting from the independent variable. The controlled variables are the factors that are not changed in the experiment between the control and experimental groups.
What is the independent variable in a controlled experiment?
The variable that affects the dependent variable. It is the variable that you control.
What is the difference between control and controlled variable?
control is when nothing is done to the experiment and controlled variable is that you have control over the experiment.
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 variable being tested and a variable being controlled?
The difference between these both is that the control is what stays the same in an experiment and the variable is what changes.
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.
What is the difference between a controlled parameter and a variable parameter?
controlled parameters the factor that stays the same in ALL groups variable parameters the factor(s) that change between control groups and variable groups
What is difference between the control group and the experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is the difference between the control group and the experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is the difference between a conrtol group and an experimental group in a controlled experiment?
The control group does not change, while the experimental group is the variable you are changing.
What is control variable and manipulated variable?
a control variable is a variable that needs to be controlled
What do controlled variable do?
You can control it that's why its called control variable.
