Understanding Density in the Metric System

The video tutorial explains the concept of density by comparing a kilogram of wood shavings to another object of the same mass. It highlights that while both have the same mass, their volumes differ due to density, which is the mass per unit volume. The tutorial further explains that density is measured in grams per cubic centimeter in the metric system. It concludes by discussing how objects with a density greater than one gram per cubic centimeter sink, while those with less density float.

What is the relationship between mass and volume in the context of the wood shavings example?

• Both objects have the same volume but different masses.

• Both objects have the same mass but different volumes.

• Both objects have different masses and volumes.

• Both objects have the same mass and volume.

How is density defined in the context of this lesson?

• The amount of volume per unit weight.

• The amount of volume per unit mass.

• The amount of mass per unit volume.

• The amount of weight per unit volume.

In which units is density measured in the metric system?

• Kilograms per cubic meter

• Grams per cubic centimeter

• Liters per kilogram

• Pounds per cubic inch

What is the density of fresh water?

• One kilogram per cubic meter

• One gram per cubic meter

• One kilogram per cubic centimeter

• One gram per cubic centimeter

What happens to objects with a density greater than one gram per cubic centimeter when placed in water?

• They remain suspended.

• They float.

• They dissolve.

• They sink.
