Marbles were dropped into these test tubes filled with oils simultaneously. Rank these oils from the one with the lowest viscosity to the one with the highest viscosity.

• SAE 20

• SAE 30

• SAE 50

• SAE 40

Look at the chart, and then place these oils in order from the ones best suited for winter use in a vehicle (first) to the ones best suited for summer use in a vehicle (last):

• 10W-60

• 0W-30

• 5W-50

• 5W-40

The speed at which a fluid goes down an incline is a measure of viscosity, and is referred to as its:

• adhesion

• flow rate
• surface tension
• cohesion

The textbook gives an anecdotal story behind the Boston Molasses Disaster of 1919. This disaster has molasses moving at speeds of over 50 km/h, and the disaster took the lives of 21 people and injured 150 more. Where did this disaster take place?

There is a special type of fluid that actually has no viscosity at all; it flows without any type of friction. Such fluids can actually flow up the sides of containers. These fluids, such as liquid helium, are called:

• non-Newtonian fluids

• superfluids

• β-fluids

• fluid²
