Step 2:
: Define Physical Properties

Physical properties are characteristics of matter that can be observed or measured without changing the substance's chemical composition. These properties are classified into two types: intensive and extensive properties.

Step 3:
: Characteristics of Intensive Properties

\begin{array}{l}
Intensive properties are: - Independent of the amount of substance - Remain constant regardless of the sample size - Examples include: \bullet \text{Temperature} \ \bullet \text{Density} \ \bullet \text{Specific Heat Capacity} \ \bullet \text{Melting Point} \end{array}

Step 4:
: Characteristics of Extensive Properties

\begin{array}{l}
Extensive properties are: - Dependent on the amount of substance - Change proportionally with the sample size - Examples include: \bullet \text{Mass} \ \bullet \text{Volume} \ \bullet \text{Total Energy} \end{array}

Step 5:
: Analyze Mass

- $$m_{total} = m_{1} + m_{2}
Mass is an extensive property because: - It changes proportionally with the amount of substance - Doubling the amount of a substance doubles its mass

Final Answer

Mass is an EXTENSIVE physical property.
