Table 1 - Physical Properties

Instructions: For color, record what you observe as the water's color for each pollution
type. For turbidity, record your observation of how clear or cloudy the water is. For
temperature, record the reading from the temperature gauge provided by the simulation.
For thermal pollution, the "rainbow" is a visual of the heat in the water. It is a heat map.

Answer 1

Physical properties are observed without changing a substance, while chemical properties involve its reactivity to form new substances. Physical changes do not alter chemical identity, whereas chemical changes produce different substances. Examples include ice melting (physical change) and coal burning (chemical change).

Step-by-step explanation:

Physical and Chemical Properties and Changes

Physical properties of a substance can be observed or measured without changing the substance's composition. Examples include color, hardness, melting point, and boiling point. Chemical properties, on the other hand, describe a substance's ability to undergo changes that transform it into different substances, like flammability or reactivity with acid.

Classifications of Changes

Physical changes are changes in state or appearance that do not alter the chemical identity of the substance. Chemical changes involve a substance reacting to form new substances with different chemical properties.

• (a) Coal burning is a chemical change.
• (b) Ice melting is a physical change.
• (c) Mixing chocolate syrup with milk is a physical change.
• (d) Explosion of a firecracker is a chemical change.
• (e) Magnetizing of a screwdriver is a physical change.

Extensive and Intensive Properties

Extensive properties depend on the amount of matter present, such as mass and volume, while intensive properties do not depend on the amount of matter, examples include density and color.
