DENSITY DENSITY DENSITY

What is the density of water?

• 0.5 g/cm³

• 1 g/cm³

• 1.5 g/cm³

• 2 g/cm³

What is the significance of density in real-world applications?

• Density is crucial for material selection and buoyancy calculations.

• Density is only important in scientific research and has no real-world applications.

• Density is irrelevant in engineering and construction.

• Density is primarily a concept used in theoretical physics.

What is density?

• Density is a measure of how much mass is contained in a given volume.

• Density is the total weight of an object regardless of its size.

• Density is the amount of space an object occupies.

• Density is the temperature at which a substance changes state.

What is the least dense object in a mixture of a cork, a fish, and a rock?

• The cork

• The fish

• The rock

• The sand

What are the two types of measurements that make up density?

• Mass and Volume

• Length and Width

• Time and Speed

• Temperature and Pressure

What is the unit of density in the metric system?

• grams per cubic centimeter (g/cm³)

• kilograms per liter (kg/L)

• pounds per cubic inch (lb/in³)

• milligrams per milliliter (mg/mL)

What is the relationship between density and buoyancy?

• An object will float in a fluid if its density is less than the density of the fluid.

• An object will sink in a fluid if its density is less than the density of the fluid.

• Density has no effect on buoyancy; all objects float equally.

• Buoyancy is only affected by the volume of the object.

How does temperature affect the density of a substance?

• As temperature increases, the density of a substance increases because the substance contracts.

• As temperature increases, the density of a substance decreases because the substance expands.

• Temperature has no effect on the density of a substance.

• As temperature increases, the density of a substance remains constant.

Why do helium balloons rise in air?

• Because helium is less dense than the surrounding air.

• Because helium is heavier than the surrounding air.

• Because helium is a gas that expands in cold temperatures.

• Because helium is lighter than water.

How can you determine the density of an irregularly shaped object?

• By measuring its mass and the volume of water it displaces when submerged.

• By calculating its weight and dividing by its surface area.

• By measuring its dimensions and using a standard density formula.

• By placing it on a scale and reading the weight directly.
