Consider each of the experiments described here. Match the correct conclusion to each experiment.
Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse.
A scientist wanted to test the relationship between pressure, force, and area to confirm that pressure equals force/area. He discovered that if the area was increased during the experiment, the pressure decreased. Assume that many trials were conducted and the force was kept constant. Based on the experiment, what relationship exists between area and pressure?
Students used a potato gun to illustrate one of the gas laws. As they decreased the volume of the air in between two pieces of potato, the pressure exerted by the gas increased. This increase in pressure eventually forces the potato out of a tube.
In a physics experiment, students collected a sample of gas at standard temperature and pressure. The volume of the gas is doubled at constant temperature with no gas leaks. Is there a change in pressure?
Experiment 1: As the area increased, the pressure decreased.
Experiment 2: As the volume decreased, the pressure increased.
Experiment 3: Doubling the volume at constant temperature does not result in a change in pressure.
To answer this question, we need to analyze each experiment and determine the relationship between area and pressure. Let's go through each experiment one by one.
1. Experiment 1:
The scientist wanted to test the relationship between pressure, force, and area. He found that when the area was increased during the experiment while keeping the force constant, the pressure decreased.
Conclusion: In this experiment, we can conclude that there is an inverse relationship between area and pressure. As the area increases, the pressure decreases.
2. Experiment 2:
The students used a potato gun to demonstrate one of the gas laws. As they decreased the volume of the air between two pieces of potato, the pressure exerted by the gas increased. This increase in pressure eventually forces the potato out of a tube.
Conclusion: In this experiment, we can conclude that there is a direct relationship between volume and pressure. As the volume decreases, the pressure increases.
3. Experiment 3:
In a physics experiment, students collected a sample of gas at standard temperature and pressure. The volume of the gas is doubled at constant temperature with no gas leaks. We need to determine if there is a change in pressure.
To solve this, we can use the ideal gas law, which states that the pressure times the volume is proportional to the number of moles of gas times the temperature.
Here, the temperature is constant, and the volume is doubled. Therefore, according to the ideal gas law, the pressure must decrease by half to maintain the equilibrium.
Conclusion: In this experiment, the pressure decreases when the volume is doubled at constant temperature.
To match the correct conclusion to each experiment, you would drag and drop the provided conclusions into the corresponding inputs for each experiment. Based on the explanations given above, the correct matches would be:
- Experiment 1: Inverse relationship between area and pressure.
- Experiment 2: Direct relationship between volume and pressure.
- Experiment 3: Pressure decreases when volume is doubled at constant temperature.
Make sure to input these conclusions into the correct response fields as instructed in the question.
