A chemist is designing an experiment to investigate the effect of temperature on the rate of a chemical change. Suggest a suitable hypothesis for the experiment. Also, list the dependent, independent, and controlled variables that can exist in such an investigation.

Question

Timmyspu · Answer

If they suggest a hypothesis about the rate of chemical change then what would a good hypothesis to go along with the rate of chemical change?

julieeeeabrilll · Answer

hypotesis..

kekeman · Answer

A good hypothesis would be "the rate of the chemical change is affected by temperature change"

....

Timmyspu · Answer

Yes that is a good, so what is the independent variable and the dependent variable?

Timmyspu · Answer

The independent variable is something that can be alone with no help but the dependent variable lies on the independent variable for help

kekeman · Answer

Dependent variable would be the "rate of chemical change'
Independent variable would be the "temperature"

Timmyspu · Answer

Correct

kekeman · Answer

How about the controlled variables?

Timmyspu · Answer

So what do you think could be the controlled variables in a chemical experiment?

kekeman · Answer

Um every other variable that is kept constant ?

I don't really know what the controlled variable is in this situation

You there?

kekeman · Answer

@vocaloid Could you help me with my controlled variable
