Front

What is the melting point of ice in degrees Celsius?

Back

0 degrees Celsius.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What type of property is malleability?

Back

Malleability is a physical property.

Front

What type of property is acidity?

Front

Define physical properties.

Back

Physical properties are characteristics of a substance that can be observed or measured without changing its chemical composition.

Front

Define chemical properties.

Back

Chemical properties are characteristics that describe a substance's ability to undergo changes that transform it into different substances.

Front

What is the significance of the boiling point in physical properties?

Back

The boiling point is the temperature at which a substance changes from a liquid to a gas, indicating its physical state under specific conditions.

Front

How does temperature affect the density of a substance?

Back

Generally, as temperature increases, the density of a substance decreases because the substance expands.

Front

What is the difference between intensive and extensive properties?

Back

Intensive properties do not depend on the amount of substance (e.g., density), while extensive properties do depend on the amount of substance (e.g., mass, volume).
