Question

1. describe high viscosity oil.
2. describe low viscosity oil.

Explanation:

For high - viscosity oil: High - viscosity oil has a thick consistency. It flows slowly. It offers more resistance to flow. It is often used in applications where a film with good load - carrying capacity is needed, like in some heavy - duty machinery at higher temperatures (to maintain its integrity).
For low - viscosity oil: Low - viscosity oil is thin. It flows easily. It has less resistance to flow. It is suitable for applications where components need to move with minimal friction, such as in some high - speed machinery or in cold environments (as it won't be too sluggish).

Answer:

1. High - viscosity oil is thick, flows slowly, has high flow resistance, and is used in applications requiring a stable film (e.g., heavy - duty machinery at high temps).
2. Low - viscosity oil is thin, flows easily, has low flow resistance, and is used in applications for minimal friction (e.g., high - speed machinery or cold conditions).
