Gas Laws and Nutrition Quiz

A sealed container holds a gas at a constant temperature. You decide to decrease the volume of the container by compressing it. What will happen to the pressure of the gas as you compress the container, assuming the temperature remains constant?

• The pressure will increase.

• The pressure will decrease.

• The pressure will remain unchanged.

• The pressure will fluctuate unpredictably.

In a laboratory experiment, you have a gas trapped in a piston at a constant temperature. You reduce the space available for the gas by pressing down on the piston. According to Boyle's Law, what is the relationship between the pressure and volume of the gas in this scenario?

• The pressure and volume are directly proportional.

• The pressure and volume are inversely proportional.

• The pressure is constant, and the volume increases.

• The volume increases as the pressure decreases.

A balloon filled with air is placed in a warm room. As the temperature in the room increases, the air inside the balloon heats up as well. What is likely to happen to the volume of the balloon as the temperature increases, assuming the pressure remains constant?

• The volume of the balloon will decrease.

• The volume of the balloon will stay the same.

• The volume of the balloon will increase.

• The volume will fluctuate with no clear pattern

You have a gas in a container with a movable piston. The temperature of the gas is raised, but the pressure is kept constant. According to Charles' Law, how will the volume of the gas change as its temperature increases?

• The volume will increase.

• The volume will decrease.

• The volume will remain the same.

• The volume will fluctuate based on temperature.

Imagine you are heating a closed container of gas. As the temperature rises, the molecules of gas start moving faster and collide with the walls of the container more often. According to the kinetic molecular theory, how does this increase in molecular speed affect the pressure of the gas, assuming the temperature is constant?

• The pressure will decrease because the molecules will move slower.

• The pressure will increase due to more frequent collisions with the container walls.

• The pressure will stay the same because the volume doesn't change.

• The pressure will decrease because the gas molecules will be spread out more.

As you dive deeper underwater, what happens to the pressure you experience?

• The pressure decreases.

• The pressure remains the same.

• The pressure increases.

• The pressure fluctuates.

Which of the following is the correct unit for measuring pressure?

• Joules (J)

• Kilograms (kg)

• Atmospheres (atm)

• Meters (m)

What is atmospheric pressure?

• The pressure exerted by gases inside a container.

• The pressure exerted by the Earth's atmosphere on objects.

• The pressure inside a vacuum.

• The pressure in a sealed container at high temperature.

Lily is recovering from surgery and her doctor recommends increasing her protein intake. Why does Lily need more protein to help her recover from surgery?

• Proteins are used to build and repair tissues in the body.

• Proteins are the primary energy source during recovery.

• Proteins help to store carbohydrates for future use.

• Proteins increase the storage of lipids for energy.

Ben is experimenting with different foods to improve his workout performance. After eating a meal with chicken (protein), rice (carbohydrates), and avocado (lipids), he notices sustained energy during his workout. Why does this combination of foods-chicken, rice, and avocado-help Ben during his workout?

• The protein helps repair muscles, carbohydrates provide energy, and lipids offer sustained energy.

• The carbohydrates provide a short burst of energy, while proteins slow down energy release.

• The lipids help in quick digestion of the protein.

• The protein stores the carbohydrates for later use during his workout.
