Density

Question 0

What equation links density, pressure, depth, and gravity

Answer 0

p = special p x g x h 
Pressure difference (Pa) = density (kg/m(cb)) x gravity (N/kg) x height (m)

Question 1

Equation for pressure force and area

Answer 1

Pressure = force/area
P = f/a
(N/m[sq] or N/cm[sq]) = N/cm(sq) or m (sq)

Question 2

Units for density

Answer 2

G/ cm (cb) or kg/m (cb)

Question 3

How do particles move in a gas

Answer 3

• collide with one another and the walls
• regularly change speed and direction
• motion appears random

Question 4

In water pressure increases with…

Answer 4

Depth and density

Question 5

Pressure acts in all ..

Answer 5

Directions

Question 6

Pressure on submerged object always acts … To its surface

Answer 6

Perpendicularly

Question 7

Units for pressure

Answer 7

Pascal

Question 8

The pressure at a given depth is … And does not depend on the … Of the vessel

Answer 8

Constant

Shape

Question 9

Equation linking density mass and volume

Answer 9

Density (spesh p) = mass(m)/volume (v)

G/kg /m(cb) = g/kg /cm/m(cb)

Question 10

Volume of a sphere

Answer 10

4/3 (pi) r(cb)

Question 11

The larger the area of an object touching the ground the …

Answer 11

Smaller the pressure is exerted and the less it is concentrated

Question 12

How to calculate the amount of force you exert on the ground

Answer 12

Force = your mass x 10

Question 13

The pressure in a fluid not only depends on the gravitational field strength but also the

Answer 13

Density and depth of the fluid
