Physical Properties are relevant to my life

Without having the knowledge of physical properties of matter, we wouldn't know how to store things, handle matter, or even deal with spills. Let's say you bought chocolate but didn't have any clue of it properties and just left it out in the heat. What would happen? It would be melted by the time you came back, of course. Knowledge of properties, like malleability and ductility, are needed when trying to make something out of a particular material. For example, gold can be used to make jewelry and copper can be used for making wires. As far as outside of school, if we didn't know we properties of water, then we'd be stuck without many different types of food such as pasta, soup, iced anything, etc. In conclusion, without knowing the physical properties of a substance, we wouldn't be able to do many advancements before we got ourselves hurt.

Physical vs Chemical Properties - Explained

# data[].attributes.body
The temperature determines the state of a substance. When energy is added, a solid changes to a liquid, and a liquid to a gas. These changes of state take places because the molecules vibrate faster when the substance is heated. When cooled (this is the process of losing heat), a gas changes to a liquid, and a liquid changes to a solid because energy is being taken away.

How is a chemical change different than a physical change?

# data[].attributes.body
A physical change takes place without any changes in molecular composition. Unlike a physical change, a chemical change produces new substances with properties different from those of the original substances. Some examples of a chemical change are combustion, electrolysis, oxidation, and tarnishing. Examples of a physical change can be bending, breaking, cutting, chopping, melting, twisting, even denting.

The melting point of water is at 100 degrees Celsius (212 degrees Fahrenheit), which is the same as the condensation point.

When trying to mix oil and water, you will see that they will separate into layers. The water has a higher density level than the oil and therefore the oil will "float" above the water

Sugar can be easily dissolved into lemon juice, therefore it has high solubility.

A way of describing how easy or difficult it is to scratch a mineral.

How soluble something is, meaning how easily it dissolves into a liquid.
