Identify the manipulated and responding variables in this testable question: "Does orange juice transform from a solid to a gas at the same exact rate as water?"

My question is, what will you be changing in this lab (MV) and what are you measuring (RV)?

you are measuring the time it takss for the OJ and water to evaporate.

the MV is the content of the two containers. One is OJ, the other H2O

In the testable question "Does orange juice transform from a solid to a gas at the same exact rate as water?" the manipulated variable (MV) would be the substance being tested, which is the orange juice. You would be comparing the rate of transformation of orange juice to the rate of transformation of water.

The responding variable (RV) in this experiment would be the rate of transformation, specifically the transformation of the substance from a solid to a gas. You would be measuring and comparing the rate at which the orange juice and water change state from solid to gas.
