Pressure Review Quiz

Abigail is diving and takes a sealed, flexible container filled with air down with her. According to Boyle's Law, what happens to the volume of the air in the container as she dives deeper, increasing the pressure around it, while the temperature remains constant?

• The volume increases.

• The volume decreases.

• The volume remains unchanged.

• The volume doubles.

Imagine Avery is conducting an experiment in a lab to observe the behavior of a helium balloon as the temperature changes. What does Charles's Law state about the relationship between the volume of the helium in the balloon and its temperature?

• The volume of the helium in the balloon is inversely proportional to its absolute temperature, assuming pressure remains constant.

• The volume of the helium in the balloon is directly proportional to its absolute temperature, assuming the quantity of helium and pressure remain constant.

• The volume of the helium in the balloon decreases as the temperature increases, assuming the quantity of helium and pressure remain constant.

• The volume of the helium in the balloon is unrelated to its temperature.

Emma is conducting a science experiment with a helium balloon. Initially, the balloon has a volume of V1 and a temperature of T1. After some time in the sun, the volume and temperature change to V2 and T2 respectively. Which equation correctly represents the relationship between the initial and final states of the balloon, according to Charles's Law?

• V1 * T1 = V2 * T2

• V1 / T2 = V2 / T1

• V1 * T2 = V2 * T1

• V1 / T1 = V2 / T2

Michael noticed that when he heats a sealed flask, the pressure inside the flask increases. What happens to the pressure when the temperature increases?

• Pressure decreases

• Pressure remains the same

• Pressure increases

• Pressure becomes zero

During a science experiment, Priya observes a helium balloon and wonders how the gas inside behaves in terms of flow. How does the gas behave?

• It does not flow

• It flows like solids

• It flows like liquids

• It flows upward only

Imagine Benjamin diving into the ocean. What depth of water would exert the same pressure as the entire atmosphere?

• A) 10 feet of water

• B) 33 feet of water

• C) 50 feet of water

• D) 100 feet of water

While snorkeling in a clear lake, Jackson starts to feel pressure against his ears. At what depth does this sensation typically begin?

• A) 3 feet

• B) 10 feet

• C) 33 feet

• D) 50 feet

While diving in a lake, Noah notices that the pressure on his diving watch increases as he swims deeper. What happens to water pressure as the depth increases?

• It decreases

• It remains the same

• It increases

• It fluctuates

Imagine Emma is diving in a deep ocean. At any given depth, how is the pressure exerted by the water around her?

• Only downwards

• Only upwards

• Equally in all directions

• Randomly in varying directions

When Henry heats a sealed container of gas, what happens to the gas molecules, causing an increase in pressure?

• The molecules move slower and collide less.

• The molecules stop moving.

• The molecules move faster and collide more.

• The molecules change state from solid to liquid.
