Which law represents the movement of gas through a small hole into an area of lower pressure?
The law that represents the movement of gas through a small hole into an area of lower pressure is known as Graham's Law of Effusion. It states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. This means that lighter gases will effuse more quickly than heavier gases under the same conditions.

What is the process by which gas particles under pressure flow through a tiny opening?
Gas particles under pressure flow through a tiny opening due to a combination of diffusion and effusion. Diffusion refers to the movement of gas particles from an area of high concentration to low concentration, while effusion specifically describes the movement of gas particles through a small opening. This process occurs until equilibrium is reached.
What is the hypothesis that explains the movement of fluid through phloem in a plant?
The hypothesis that explains the movement of fluid through phloem in plants is known as the "pressure flow hypothesis." It posits that the movement of sap, which contains sugars and nutrients, occurs due to differences in turgor pressure between source tissues (where sugars are produced or stored) and sink tissues (where they are utilized). As sugars are actively loaded into the phloem at the source, water enters osmotically, creating high pressure that drives the flow of the sap toward areas of lower pressure at the sinks.
What is Flowing air responding to the difference between higher and lower pressure is responding to what?
Flowing air responds to the difference in pressure between higher and lower pressure areas by moving from high pressure to low pressure to equalize the pressure. This movement of air creates wind, which is the result of the pressure difference seeking equilibrium.
What do the 2 numbers in blood pressure represent?
The first number in a blood pressure reading is the systolic blood pressure. It represents the pressure in the artery when the heart is contracting. The second number is the diastolic blood pressure, and represents the pressure when the heart is relaxing.
Demonstrate that Air movement can result in lift?
Air movement can result in lift through the generation of pressure differences. When air moves faster over the curved upper surface of a wing compared to the slower-moving air beneath the wing, it creates lower pressure above and higher pressure below the wing. This pressure difference generates lift, causing the wing and the object it's attached to (like an airplane) to rise.
The movement of gas through a small hole into an area of lower pressure is?
The movement of gas through a small hole into an area of lower pressure is diffusion.
The movement of gas through a small hole into an area of lower pressure is called?
EFFUSION
The movement of fluid through the cell membrane from a high pressure area to a lower pressure area is called?
The movement of fluid through the cell membrane from a high pressure area to a lower pressure area is called osmosis. Osmosis is a passive process that allows water molecules to move across a semipermeable membrane to equalize concentrations on both sides of the membrane.
What is the part of the wave that represents the lower air pressure?
The tip of the wave.
IS The movement of substances from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure is called diffusion?
No, the movement of substances from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure is not called diffusion. Diffusion is the movement of substances from an area of higher concentration to an area of lower concentration. The movement of substances from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure is called filtration. Filtration is a passive process driven by the pressure difference across a membrane.
What is the source of wind?
The movement of air from an area of higher pressure to one of lower pressure
What is the process by which gas particles under pressure flow through a tiny opening?
Gas particles under pressure flow through a tiny opening due to a combination of diffusion and effusion. Diffusion refers to the movement of gas particles from an area of high concentration to low concentration, while effusion specifically describes the movement of gas particles through a small opening. This process occurs until equilibrium is reached.
What happens when air hits an area of lower pressure?
Air flows from higher pressure to lower pressure, creating winds as it moves to balance out the pressure difference. This movement of air is known as wind, and it is responsible for weather patterns and changes in the atmosphere.
What is Flowing air responding to the difference between higher and lower pressure is responding to what?
Flowing air responds to the difference in pressure between higher and lower pressure areas by moving from high pressure to low pressure to equalize the pressure. This movement of air creates wind, which is the result of the pressure difference seeking equilibrium.
What do the 2 numbers in blood pressure represent?
The first number in a blood pressure reading is the systolic blood pressure. It represents the pressure in the artery when the heart is contracting. The second number is the diastolic blood pressure, and represents the pressure when the heart is relaxing.
Which of the choices below determines the direction of respiratory gas movement?
The direction of respiratory gas movement is determined by the difference in partial pressure of a gas between two areas. Gas moves from areas of higher partial pressure to areas of lower partial pressure to equalize the pressure.
Demonstrate that Air movement can result in lift?
Air movement can result in lift through the generation of pressure differences. When air moves faster over the curved upper surface of a wing compared to the slower-moving air beneath the wing, it creates lower pressure above and higher pressure below the wing. This pressure difference generates lift, causing the wing and the object it's attached to (like an airplane) to rise.
