Question

05 multiple choice
according to the following viscosity lab data, which liquid is the most viscous?
liquid | distance traveled (cm) | time (s)
--- | --- | ---
mineral oil | 11.5 | 6.53
corn oil | 11.5 | 1.83
40 motor oil | 11.5 | 8.28

mineral oil
corn oil
40 motor oil

Explanation:

Step1: Define viscosity relation

Viscosity is inversely related to flow speed; slower flow = higher viscosity.

Step2: Compare travel times

All liquids travel 11.5 cm. Times:

• Mineral oil: 6.53 s
• Corn Oil: 1.83 s
• 40 Motor Oil: 8.28 s

Step3: Identify slowest flow

8.28 s is the longest time, so 40 Motor Oil flows slowest.

Step4: Conclude highest viscosity

Slowest flow corresponds to highest viscosity.

Answer:

40 Motor Oil
