PS Part 2 Final Review

What causes ice to float in water?

• Ice is heavier than liquid water

• Ice is less dense than liquid water

• Ice is more dense than liquid water

• Ice is the same density as liquid water

What is buoyancy?

• The ability of a solid to sink in a liquid

• The ability of a fluid to push an object upward

• The ability of a gas to expand

• The ability of a liquid to contract

According to Pascal’s principle, what happens when pressure is applied to a fluid?

• It is transmitted equally throughout the fluid

• It decreases in the fluid

• It only affects the surface of the fluid

• It causes the fluid to evaporate

What does Bernoulli’s principle state about the speed of a fluid?

• As the speed of a fluid increases, its pressure increases

• As the speed of a fluid increases, its pressure decreases

• As the speed of a fluid decreases, its pressure decreases

• As the speed of a fluid decreases, its pressure remains constant

What is a heterogeneous mixture?

• A mixture made of one type of element

• A mixture where the different materials are clearly visible

• A mixture where the different materials are not visible

• A mixture that cannot be separated

Ice is less dense than liquid water because:

• Ice is heavier than water

• Ice is less dense than liquid water

• Ice has more molecules than water

• Ice contracts when it freezes

According to Archimedes’ principle, an object floats if:

• Its weight is more than the buoyant force

• The fluid is very viscous

• The buoyant force is equal to or greater than its weight

• It is made of metal

Which law states that increasing the temperature of a gas (at constant pressure) increases its volume?

• Boyle’s Law

• Charles’s Law

• Pascal’s Law

• Archimedes’ Law

Which of the following is an example of a homogeneous mixture?

• Salad

• Sand and water

• Saltwater

• Oil and water

What is viscosity?

• The color of a fluid

• The resistance of a fluid to flow

• The density of a fluid

• The temperature of a fluid
