The single factor that is changed in an experiment is the?
the dependent variable is the only thing that changes in an experiment
Is hammering metal into a flat sheet physical change?
Yes it is a physical change. The only other option is chemical change and the metal didnt change its chemical make up, it only changed its shape, and shape is the only thing that did change.
Why do you only change 1 thing in a lab?
because that one thing will be the variable. if you change more than one thing, the experiment will come out with a different answer because more than one thing is being changed, its like growing two plants, one with miracle grow and one without. you put the one with miracle grow in the sun and is watered often, while the other plant is put in a dark room and watered the same amount. in that situation, the variable is supposed to be the miracle grow but the lack of sunlight on the other plants gives you tainted results.
Melting of ice chemical or physical change?
Melting ice is a physical change, because there is no new substance formed. The only thing that changes is the state of matter.
A controlled experiment is one in which only one is changed at a time?
Variable
What type of variables are in experiment?
the only variables in an experiment are the independent variables [the thing in an experiment your going to change. and the dependent variables [the thing in an experiment your going to measure.
Why is important to test only one thing at a time in a controlled experiment?
Because if you change more than one thing at the same time, you can't say which one caused a change in the result.
Why is it imporatant to change systematically only one variable at a time when doing the experiment?
It is important to only change one variable at a time when doing an experiment, because if you change more than one, there will be uncertainty as to which one affected the result.
What is The thing you change in an experiment?
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
How do you make an experiment a fair test?
Repeat the procedure at least twice, preferably 3 times. Only keep 1 thing in your experiment the same. Change the materials or anything you are using.
The single factor that is changed in an experiment is the?
the dependent variable is the only thing that changes in an experiment
How many things can you change in an experiment?
You only change 1 iv ( independent variable in a experiment ) HOPE IT HELPS :)
Why do you only change one variablle at a time in a science experiment?
So that you can see the difference in your experiment.
Why is it important to only test one variable in an experiment?
Because if you change more than one variable at a time, you can't tell which is affecting the results.
What is any factor that is not allowed to change in an experiment called?
A constant. It is important to ensure that only one factor changes in an experiment (called the independent variable). All other factors need to remain constant.
Did the color of Copper ( ) sulfate change?
We can not answer this as we were not there to observe the experiment. Only YOU can answer this!
How many variables would you change in a controlled experiment?
You can only change ONE at a time. That's what makes it controlled. It's the only sure way to know what actually changed the experiment.
