Question

In a lesson about the behavior of gases, Genaris and her classmates learn that the volume of a gas is affected by its temperature. They formulated a hypothesis: If the temperature of a gas increases, the volume of the gas will increase because the increased temperature will increase the kinetic energy of the particles, which will then result in the expansion of the gas. The results of their experiment supported the hypothesis. They wanted to know if there were other factors that affect the volume of a gas. What would Genaris and her classmates most likely do to test this idea? They would formulate a new hypothesis with the same independent variable but a different dependent variable as the original hypothesis. They would formulate a new hypothesis with a different independent and dependent variable as the original hypothesis. They would formulate a new hypothesis with the same dependent variable but a different independent variable as the original hypothesis. They would formulate a new hypothesis that has the independent and dependent variables of the original hypothesis switched.

Answer 1

The correct answer is

B). They would formulate a new hypothesis with the same dependent variable but a different independent variable as the original hypothesis.

Answer 2

To know if there were other factors that affected the volume of a gas, Genaris and her classmates should: "formulate a new hypothesis with the same dependent variable but a different independent variable as the original hypothesis." In this case, the dependent variable is the volume of the gas and the new independent variable is a factor they think will affect the volume of the gas.
