Physical Properties

These flashcards cover the key concepts related to physical properties of substances, their types, and examples.

What are properties in the context of substances?

Characteristics that describe a substance using our senses.

List the five senses used to describe physical properties.

Sight, Sound, Smell, Touch, Taste.

What are observed properties?

Qualitative properties that do not have a numerical value and use senses to describe a substance.

Provide examples of qualitative properties.

Colour, Odour, Texture.

What are measured properties?

Quantitative properties that have a numerical value and use numbers to record observations.

Provide examples of quantitative properties.

Temperature, Height, Mass, Volume.

What is a state in physical properties?

The form a substance takes; can be solid, liquid, or gas.

Define hardness in terms of physical properties.

The ability to be scratched by another substance; harder substances are more resistant to scratching.

Give an example of a hard substance.

Diamonds.

What does malleability refer to?

The ability of a substance to be hammered into a thinner sheet or molded into shape.

Provide an example of a malleable substance.

Copper.

Define brittleness in physical properties.

How breakable or flexible a substance is.

Give an example of a brittle substance.

Glass.

What does ductility refer to?

The ability of a substance to be pulled into wires.

Provide examples of ductile substances.

Aluminum and Copper.

Define melting point.

The temperature at which a substance changes from solid to liquid.

What is the melting point of water?

0ºC.

Define boiling point.

The temperature at which a substance changes from liquid to gas.

What is the boiling point of water?

100ºC.

What is viscosity?

The ability of a substance to resist flow; thicker liquids are more viscous.

Provide an example of a viscous substance.

Maple syrup.

Define solubility.

A substance is soluble if it dissolves in a liquid, usually water.

Provide an example of a solubility property.

Kool-aid crystals dissolving in water.

What does lustre refer to in physical properties?

How shiny or dull a substance is and how it reflects light.

Provide an example of a shiny and a dull substance.

Silver (shiny), Wood (dull).

What is clarity in terms of physical properties?

The ability to allow light through; can be clear, translucent, or opaque.

Provide examples of a transparent, translucent, and opaque substance.

Glass (transparent), Frosted glass (translucent), Concrete (opaque).

What are the characteristics of observations in the Inquiry Lab?

Based on the 5 senses, are factual, and use descriptive words without opinions.
