Physical Properties of Matter - Review

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in grams or kilograms.

Front

What is density?

Back

Density is a measure of how much mass is contained in a given volume, calculated as mass divided by volume.

Front

Why is density useful for identifying substances?

Back

Density remains constant regardless of the size of the sample, making it a reliable property for identification.

Front

What is thermal conductivity?

Back

Thermal conductivity is a measure of a substance's ability to conduct heat across the material to another object.

Front

What does a physical change mean?

Back

A physical change refers to a change in the state of matter where the material remains the same type with the same properties as the original.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is a physical property of matter?

Back

A physical property is a characteristic of a substance that can be observed or measured without changing its identity.

Front

What is an example of a physical change?

Back

Melting ice is an example of a physical change, as it changes from solid to liquid but remains water.

Front

What is the significance of specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
