When you increase your depth under water, the water pressure on your body

• increases

• decreases

• stays the same

• changes direction

Which of the following would increase the pressure in a metal gas cylinder?

How do you Calculate Pressure

• Force /Area

• Force x Area

• Area /Force

• Mass / Area

Why won't you sink in mud if you wear wide boots?

• Because the surface area is larger creating less pressure.

• They have air inside to keep you floating.

• Because the mud is brown.

• The pressure is higher because of the larger area

• The design of this structure is stronger at the top.

• Water pressure increases with depth.

• The cost of construction is lower.

• Water pressure acts in one direction to push on the wall.
