A controlled experiment. In a controlled experiment, all variables apart from the independent variable are kept constant to accurately determine the effect of the independent variable on the dependent variable. This helps ensure that any observed changes are due to the manipulated variable and not other factors.
Temperature and the amount of gas (moles) must be kept constant for Boyle's law to hold true. This means the pressure and volume of a gas are inversely proportional provided the temperature and amount of gas remain constant.
A control setup for this investigation would be identical to the one described except for the replacement of the independent variable being tested. This means that all other experimental conditions, materials, and procedures would remain the same to ensure that any observed effects can be attributed solely to the manipulated variable. By keeping everything else constant, the control group serves as a baseline for comparison against the experimental group.
pressure did not remain constant or if the amount of gas did not remain constant.
Keeping all variables constant or unchanged in an experiment is crucial to ensure that any observed effects can be confidently attributed to the independent variable being tested. This control helps eliminate confounding variables that could skew results, making it difficult to draw accurate conclusions. By isolating the variable of interest, researchers can establish clearer cause-and-effect relationships and enhance the reliability of their findings.
The total mass remain constant after a chemical reaction.
Controlled variables are quantities that must remain constant.
It means that except for the independent variable (the only factor that you change) you remain the other variables constant. To keep the control variables the same. Then this is a controlled experiment (fair test). Hope this helps :)
because i have bstl
Controlled variables are quantities that a scientist wants to remain constant and observe as carefully as the dependent variables.
Independent and Dependent Variables
Variables that remain constant in a scientific experiment are called controlled variables. These variables are not changed throughout the experiment to ensure that any observed effects are due to the independent variable being tested.
A constant variable in research method is a factors or quantities that never change. Constant variables always remain the same.
In Boyle's law, the constant is the temperature of the gas. The variables are the pressure and volume of the gas. Boyle's law states that at a constant temperature, the pressure of a gas is inversely proportional to its volume.
Variables that should remain the same in an experiment to have a fair test of the independent variable are called control variables. These include factors such as temperature, time of day, equipment used, and method of measurement. By keeping these control variables constant, any observed effects in the experiment can be confidently attributed to changes in the independent variable.
The independent variable is the condition that changes in an experiment while all the other variables remain constant. The purpose of changing this variable is to observe its effect on the dependent variable.
