Takeaways

Which statements below is INCORRECT about liquids and gases?

• Liquids possess greater kinetic energy than gases.

• Gases have weak molecular force of attraction while liquids have a moderate force of attraction.

• Liquids have a definite size where gases can expand to fill any closed container.

• Gases are easily compressed where liquids are not.

What does viscosity mean?

• How close the particles are together.

• The amount of matter in a substance.

• How easily a fluid flows.

• How dense a fluid is.

Fluid pressure is directed

• in all directions.
• only upward.
• only downward.
• always sideways.

Fluids flow

• only when warmed up.
• from regions of low pressure to regions of high pressure.
• until evenly spread out.
• from high to low pressure.

High viscosity can be described as...

• a liquid that flows quickly

• a liquid that flows slowly
