Question

question 11
viscosity is the characteristic of a fluid that resists

• solidifying
• floating
• flow
• mixing with other liquids

question 12
1 pts
friction converts the energy of motion to energy.

• chemical
• heat
• electrical
• potential

Explanation:

• Question 11: Viscosity is a property of fluids. It is defined as the resistance of a fluid to flow. For example, honey has a high viscosity (resists flow more) compared to water (low viscosity). So, viscosity resists flow.
• Question 12: Friction is a force that opposes motion. When two surfaces rub against each other (due to friction), the mechanical energy (energy of motion) is converted into heat energy. This can be felt when you rub your hands together - they get warm.

Answer:

• Question 11: flow
• Question 12: heat
