2.1 Materials Matter Practice Flashcard

Front

What property would you assess to determine if a material can conduct heat?

Back

Thermal conductivity is the property that indicates how well a material can conduct heat.

Front

Which of the following is an example of a physical property?

Back

Color is a physical property that describes the appearance of a material.

Front

What is the base unit of measurement for mass?

Back

The base unit of measurement for mass is the gram.

Front

What happens to the density of an object if its mass increases while its volume remains constant?

Back

Density increases when the mass of an object increases while its volume remains constant.

Front

How do you calculate the volume of a rectangular solid?

Back

Volume = length × width × height.

Front

What is the volume of a solid with a length of 4, width of 3, and height of 2?

Back

The volume is 24 cubic units.

Front

What is the definition of density?

Back

Density is the mass of an object divided by its volume (Density = Mass/Volume).

Front

What is an example of a chemical property?

Back

Reactivity with acid is an example of a chemical property.

Front

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form of a substance without changing its identity, while a chemical change results in the formation of new substances.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.
