Viscosity - Forces, Fluids, and Density Test

Question 1

Define the following word: Viscosity

Answer 1

Viscosity is the measurement of a fluid’s resistance to flow

Question 2

Define the following word: Liquid

Answer 2

a substance that flows freely but is of constant volume, having a consistency like that of water or oil.

Question 3

Define the following word: Pressure

Answer 3

continuous physical force exerted on or against an object by something in contact with it.

Question 4

Define the following word: compress

Answer 4

To change shape, such as to be flatten or pressed using pressure

Question 5

Define the following word: compressibility

Answer 5

The compacity of an object or something to be flattened or reduced in size or volume using pressure

Question 6

Define the following word: hydraulic

Answer 6

denoting, relating to, or operated by a liquid moving in a confined space under pressure.

Question 7

Define the following word: Pneumatic

Answer 7

containing or operated by air or gas under pressure.

Question 8

Answer the following question -
Explain how temperature affects viscosity?

Answer 8

Viscosity will decrease in increase with temperature, so meaning the colder it is, the higher viscosity it has but the hotter the temperature, the lower viscosity it has. This is because when things are hotter, the particles in that object are father apart and have more energy unlike the particles in a colder object as the particles are closer together and has less energy.

Question 9

Answer the following question -
explain how the ramp and bubble method can be used to compare viscosities.

Answer 9

ramp - by pouring down different liquids at the top of the ramp, it measures the viscosity as the slower the liquid flows down the ramp, the more viscosity it has. But the faster the liquid flows down the ramp, the less viscosity it has.

bubble - by filling tube containers with different liquids and leaving it with some small gas volume, you can measure the viscosity it has flipping the tube over. The faster the bubble travels from the bottom of the tube to the top of the tube through the liquid, the lower the viscosity it has, but the slower it travels from the bottom to the tube to the top through the liquid, the more viscosity it has.

Question 10

Answer the following question -
explain why viscosity relates to the quality and choice of products?

Answer 10

Ketchup - When picking up a ketchup, you would want a medium viscosity of ketchup, not to much viscosity or the ketchup would be to liquidly but if it has to much viscosity, it would be to thick to slide on the hotdog and spread.
