G9 Pressure Quiz

What is hydrostatic pressure?

• Pressure exerted by a solid object due to the force of gravity.

• Pressure exerted by a gas at rest due to the force of gravity.

• Pressure exerted by a fluid in motion due to the force of gravity.

• Pressure exerted by a fluid at rest due to the force of gravity.

Explain the concept of pressure in fluids.

• Pressure in fluids refers to the speed of the fluid.

• Pressure in fluids refers to the color of the fluid.

• Pressure in fluids refers to the temperature of the fluid.

• Pressure in fluids refers to the force exerted by the fluid per unit area.

What are some common methods used to measure pressure?

• Thermometers, hygrometers, and altimeters

• Thermocouples, thermistors, and pyrometers

• Tachometers, flowmeters, and viscometers

• Mercury barometers, aneroid barometers, manometers, and pressure transducers

Describe the relationship between pressure and temperature.

• Pressure has no effect on temperature.

• Pressure and temperature are inversely proportional.

• Pressure and temperature are directly proportional.

• Temperature increases as pressure decreases.

What is the formula to calculate hydrostatic pressure?

• P = ρg

• P = ρg^2

• P = ρgh

• P = ρg^3

What is Pascal's law?

• Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.

• Pascal's law states that pressure increases at a different rate at every other point in the container when there is an increase in pressure at any point in a confined fluid.

• Pascal's law states that pressure remains constant at every point in the container when there is an increase in pressure at any point in a confined fluid.

• Pascal's law states that pressure decreases at every other point in the container when there is an increase in pressure at any point in a confined fluid.

How does pressure change with depth in a fluid?

• Pressure decreases with depth.

• Pressure remains constant with depth.

• Pressure fluctuates randomly with depth.

• Pressure increases with depth.

What is the SI unit of pressure?

• m

• Pa

• kg

• N

Explain the concept of atmospheric pressure.

• Atmospheric pressure is caused by the movement of tectonic plates.

• Atmospheric pressure is the result of the Earth's magnetic field.

• Atmospheric pressure is the force exerted by the weight of the air in the Earth's atmosphere.

• Atmospheric pressure is caused by the rotation of the Earth.

How does pressure affect the boiling point of a liquid?

• Increasing pressure increases the boiling point of a liquid.

• Increasing pressure decreases the boiling point of a liquid.

• Pressure has no effect on the boiling point of a liquid.

• Increasing pressure causes the liquid to freeze instead of boiling.
