What is a Independent variable, dependent variable, and controlled variable in the question below.?

Does temperature affect the reaction rate of alka seltzer?





if you need any more information e-mail me at femtun1234@yahoo.comWhat is a Independent variable, dependent variable, and controlled variable in the question below.?
the reaction rate is the dependent variable as it depends on the temperature....assuming that is what ur question means.


the temperature is the independent variable as its value does not depend on any other thing.


if it is varied according to user, the temperature acts as the controlled variable as it is under ur control.





hope this is what u wanted n i hav helped u.What is a Independent variable, dependent variable, and controlled variable in the question below.?
In this experiment you're controlling the temperature to see the reactions in the alka seltzer right?





Controlled Variable: The temperature because you are changing and *controlling* it to make the reactions different in the seltzer.





Independent Variable: The alka seltzer because it doesn't change in this experiment and it would be fine *independently*





Dependant Variable: The reaction because you can't have a reaction unless you have a cause so it is *dependant* on the temperature and alka seltzer.





hope this helped :)
