Pressure

How does depth affect fluid pressure?

• Fluid pressure decreases with depth due to the weight of the fluid above.

• Fluid pressure remains constant regardless of depth.

• Fluid pressure increases with depth due to the weight of the fluid above.

• Fluid pressure is only affected by temperature, not depth.

What is pressure?

• Pressure is the amount of force applied to an object without regard to area.

• Pressure is defined as the force applied per unit area on a surface.

• Pressure is the total weight of an object divided by its volume.

• Pressure is the measure of how much mass is contained in a given volume.

How does temperature affect gas pressure?

• Increasing the temperature of a gas increases its pressure if the volume is held constant.

• Decreasing the temperature of a gas decreases its pressure if the volume is held constant.

• Temperature has no effect on gas pressure regardless of volume.

• Increasing the volume of a gas increases its pressure if the temperature is held constant.

How can pressure be measured?

• Using a thermometer

• Using a manometer

• Using a voltmeter

• Using a hygrometer

What is atmospheric pressure?

• The pressure exerted by the weight of the atmosphere above a given point.

• The pressure exerted by the weight of water in the oceans.

• The pressure created by the movement of tectonic plates.

• The pressure experienced at sea level only.

What is fluid pressure?

• Fluid pressure is the pressure exerted by a fluid at rest due to the weight of the fluid above it.

• Fluid pressure is the force exerted by a fluid in motion.

• Fluid pressure is the pressure exerted by a solid object in a fluid.

• Fluid pressure is the pressure experienced by a fluid due to temperature changes.

How does fluid pressure differ from pressure in solids?

• Fluid pressure is generated by particle collisions in all directions, while solid pressure is typically exerted in a specific direction.

• Fluid pressure is exerted in a specific direction, while solid pressure is generated by particle collisions in all directions.

• Fluid pressure is always higher than solid pressure regardless of the conditions.

• Fluid pressure acts only on the surface of solids, while solid pressure acts throughout the material.

What happens when a gas particle collides with the wall of its container?

• It creates a vacuum in the container.

• It applies a force to the wall, creating pressure.

• It causes the gas to expand indefinitely.

• It cools down the gas particles.

What is the unit of pressure?

• Pascal (Pa)

• Bar (Ba)

• Atmosphere (atm)

• Torr (mmHg)

What is gauge pressure?

• The pressure relative to atmospheric pressure.

• The total pressure exerted by a fluid.

• The pressure measured at sea level.

• The pressure in a vacuum.
