The viscosity of a gas increases as its heated and decreased as it is cooled. The opposite occurs in a liquid.

The buoyant force acting on an object that is submerged in a fluid equals the weight of the fluid that is displaced by the object. This describes which principle?

This is the measurement of the amount of space that is occupied by a substance.

This is achieved when an object neither rises nor sinks in a fluid. This allows fish to stay at a constant depth of water.

This is the amount of mass in a certain volume of a substance.

"Solids are more dense than liquids." Is this statement true?

Someone decides to dump machine oil into a pond, thinking that the oil will mix with the water and "disappear." Mrs. Frizzle explains, "Any dumping of oil harms the environment. The machine oil is less dense than the water, so it will float on the water rather than mix in a "disappear"." Is Mrs. Frizzle correct?

This unit is used to measure pressure.

The device used for measuring air pressure.

The study of the pressure of gases and the systems that use gas pressure.

The ability to be squeezed into a smaller volume.

The study of the pressure of liquids.

Mrs. Quinton lists four devices that use either pneumatics or hydraulics: tampers, trucks/buses, car lifts, and dentist tools. Is she correct?

Which substance has the highest density if it is contained within an identical container as the others?

Which of the following statements is true?

This word describes a push or pull, or anything that causes a change in the motion of an object.

What is the mass of a piece of iron, if the volume is 5 cm³ and the density is 11.34 g/cm³?

What is the volume of sugar, if it has a mass of 10 g? The density of sugar is 1.59 g/cm³.

Read the following statements to determine which is/are true.

A. The buoyant force acting on an object equals the weight of the fluid displaced by the object.

B. The buoyant force does not depend on the weight of the submerged object, but rather the weight of the displaced fluid.

C. The buoyant force that pushes up against an object immersed in water is less than the weight of the fluid that the object displaces.

The buoyant force on an object equals:

Read the following statements to determine which is/are true.

A. The density of freshwater is greater than the density of salt water.

B. Salt water can support more weight per volume than fresh water.

C. The buoyant force of a liquid does not depend on physical state, but rather on density.

Buoyancy is described as:

Which of the following explains why a ship made of steel can float?

Sugar juice crystals has a solubility of 180g/100mL. Your juice container is 500 mL and you want to make your juice perfectly saturated. How many grams of juice crystals do you need to dissolve into the 500 mL?
