What is the SI unit of pressure?
Kg/m3
Pa
kg m-3
N m2
What is the formula for pressure?
P = F / A
P = F A
P = A / F
F = P / A

only when warmed up.
from regions of low pressure to regions of high pressure.
until evenly spread out.
from high to low pressure.
If an object has a density of 3.6 g/mL and you put it into water (density =1.0g/mL,) will it sink or float?
sink
float
partially sink
partially float
When you increase your depth under water, the water pressure on your body
increases
decreases
stays the same
Calculate the pressure at the bottom of a cylindrical vessel filled with water.Area of cross section is 250 cm2. density of water is 1000 kg m-3. water is filled to a height of 10cm.
g = 10 ms-2
250 Pa
105 Pa
2500 Pa
1000 Pa
When a diver dives deeper into the ocean, he will experience ...................... liquid pressure
greater
less
no
These are Pascal's Vases. What would happen if you poured water into the right-hand tube?
The water would fill up the right hand tube before flowing to the others and filling them up.
The thinner tubes would fill up more than the thicker tubes
The thicker tubes would fill up further than the thinner tubes
The height of the water would be the same in all the tubes.
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.
