Measuring volume and density

Question 1

How is volume determined by? (3 points)

Answer 1

1. viewing the measurement of a liquid in a container
2. volume of a rectangular prism
3. using a displacement method in a container to measure an irregular shaped object

Question 2

How to measure volume

Answer 2

we use volumetric flasks/graduated flasks to measure volume precisely.
when we read the reading, we look at the lowest point of the meniscus

Question 3

What is the metric system?

Answer 3

an international system of measuring (based on multiple of 10)

Question 4

What is a fluid?

Answer 4

a fluid is any form of matter that can flow

Question 5

Are liquids and gases fluids?

Answer 5

yes, since they do not have a fixed shape or volume.

Question 6

Are solids fluids?

Answer 6

no, since they have a fixed shape

Question 7

What is density?

Answer 7

density is the amount of material (mass) for each unit of space it occupies (volume)

Question 8

Density and layers of fluids:

Answer 8

-fluids that do not mix separate themselves according to their density.
-less dense fluids settle on top of more dense fluids.

Question 9

What is the equation for density?

Answer 9

mass/volume

Question 10

Buoyancy:

Answer 10

it is a physical property that is directly proportional to the density of the fluid in which an object immersed in a fluid.

Question 11

What is the formula for buoyancy:

Answer 11

Fb=-pgV=-DgV

Question 12

Viscosity: 2 points

Answer 12

is a physical property that can be used to describe liquids
it is the measure of resistance to deformation at a given rate.
