Question

experiment: a student put nitrogen gas into an airtight cylinder with a piston that could be exerted down to decrease the volume of the container. the student measured the pressure of the gas at three different container volumes using a pressure probe. the mass of the gas did not change. match each part of the experiment with the correct term. dependent variable independent variable hypothesis constant volume of the container mass of nitrogen gas if the volume of the container decreases, then the pressure of the gas will increase pressure of gas

Explanation:

• Dependent Variable: The variable that depends on the independent variable. In this experiment, the pressure of the gas depends on the volume of the container, so the dependent variable is the pressure of gas.
• Independent Variable: The variable that is manipulated. Here, the student changes the volume of the container, so the independent variable is the volume of the container.
• Hypothesis: A testable prediction. The statement "If the volume of the container decreases, then the pressure of the gas will increase" is a hypothesis.
• Constant: The variable that stays the same. The mass of the nitrogen gas does not change, so it is the constant.

Answer:

• Dependent Variable: pressure of gas
• Independent Variable: Volume of the container
• Hypothesis: If the volume of the container decreases, then the pressure of the gas will increase
• Constant: mass of nitrogen gas
