Question

During a laboratory experiment, the temperature of the gas in a balloon is varied and the

volume of the balloon is measured.

A)

Which quantity is the independent variable?

B)

Which quantity is the dependent variable?

Answer 1

A. The IV is the temperature of gas in the balloon.

B. The DV is the volume of the balloon.
