Define a physical Property, and give one example.
The properties that can be observed without the change of the substance
Color & Appearance: What you see, such as the silver-grey look of iron or the reddish-brown tint of copper.
State of Matter: Whether a substance is a solid, liquid, gas, or plasma at a given temperature.
Melting & Boiling Points:
- Density: How much mass is packed into a specific volume
- Hardness: How resistant a solid material is to permanent shape change or scratching (e.g., diamond is much harder than graphite).
- Conductivity: How well a material allows heat or electricity to flow through it (e.g., copper conducts electricity well).
- Malleability & Ductility: How easily a solid can be hammered into thin sheets (malleability) or drawn into wires (ductility).
Solubility:
- Magnetism

Define chemical properties and give me one example
These are properties that can only be seen through chemical reactions:
- Flammability: The ability of a substance to burn or ignite in the presence of oxygen and a heat source.
Toxicity: The degree to which a chemical substance can damage or harm a living organism.
Reactivity: How readily a substance undergoes a chemical change when combined with other elements or compounds.
Oxidation / Corrosion: The tendency of a material (like metals) to lose electrons or react with oxygen and moisture to form oxides, such as rust.
- Acidity and Basicity (pH): A measure of how acidic or basic a solution is based on hydrogen ion concentration.
- Heat of Combustion: The amount of energy released when a substance undergoes complete combustion.

what happens to the heat in a substance when it moves from a liquid to a solid?
The heat leaves the substance causing it to freeze

What is a chemical that you can find in your house? What is the danger of the chemical and what WHMIS symbol would you give it
Lots of different examples

When making icecream, why do we add salt to the ice mixture?
The salt lowers the freezing point of water. When the ice melts heat is transferred more rapidly from the cream mixture to the ice, giving us icecream

Jesse is certain that when water changes states it goes through chemical change. Are they right or wrong? How would you explain the right answer?
Jesse is incorrect, the properties of water never change, the particles are always water, changing states only changes how fast they move and how far apart they become.
