This is an example of the everyday application of pressure in:
Solids
Liquids
Gases
Plasma
The pressure inside the syringe will decrease if we move the plunger in:
Direction A
Direction B
We don't have to move the plunger as the pressure will change on its own.
None of the above answers.
We can increase the pressure of a gas by:
Adding more gas.
Reduce the volume of the container.
Increase the temperature of the gas.
None of the above answers.
Weather balloons travel to a great height gathering data before the balloon bursts. This is because the atmospheric pressure (layer of gas surrounding the earth):
Increases the higher you travel.
Decreases the higher you travel.
Remains the same.
Not enough information to answer the question.
The reason gases can be compressed is because:
The particles are very close together.
The particles are merely vibrating.
The particles are unable to move.
The particles are very far apart.
When you increase your depth under water, the water pressure on your body
increases
decreases
stays the same
How do you Calculate Pressure
Force(N)/Area(m2)
Force(kg)/Area(mi2)
Area(m2)/Force(N)
Why won't you sink in mud if you wear boots?
Because the surface area is larger creating less pressure.
Has air in it to keep you floating.
Because the mud won't want you.
Diagram shows the design of a dam. Why does the thickness of the dam increase with its depth?
The design of this structure is stronger.
Water pressure increases with depth.
The cost of construction is lower.
Water pressure acts uniformly in all directions.
What is pressure?
