06 Pressure and Density

Question 1

Define density

Answer 1

The mass per unit volume

Question 2

How do you find the volume of a cuboid object?

Answer 2

Multiply the height, width, length (h x w x l)

Question 3

Give the equation linking pressure, force and area:

Answer 3

p = F/A
(pressure [pa] = Force (N)/ area [,m^2])

Question 4

What is 1 atm (atmopsphere) equivalent to?

Answer 4

101 325 Pa

Question 5

what is density a measurement of?

Answer 5

how heavy something is per measurement of how big it is.

Question 6

what is the greek letter that represents density?

Answer 6

ρ (rho)

Question 7

give the equation linking pressure, force and area

Answer 7

pressure = force/area

Question 8

define atmospheric pressure

Answer 8

the weight of the atmosphere (force) over the Earth’s area

Question 9

1 atm =

Answer 9

101300 Pa

Question 10

give the equation linking pressure, change in height, density, and the strength of gravity

Answer 10

pressure = change in height + density + strangth of gravity

Question 11

what is the unit of density?

Answer 11

kilograms per metre cubes (kg/m^3)
