4 &5 Physical and Chemical Properties of Matter (Definition)

physical property

• A characteristic of a pure substance that describes its ability to change into different substances
• A characteristic of a pure substance that can be observed without changing it into another substance
• A measure of how easily a substance can be scratched
• a liquid's resistance to flow

texture

• The feel, appearance, or consistency of a substance
• a measure of the tendency of a chemical compound to maintain its original chemical composition rather than break down to form a different chemical
• the process by which molecules move from an area of higher concentration to an area of lower concentration
• The way a substance reflects light

• a measure of the tendency of a chemical compound to maintain its original chemical composition rather than break down to form a different chemical
• A characteristic of a pure substance that describes its ability to change into different substances
• smell

sound

• The ease and speed with which an element combines, or reacts, with other elements and compounds.
• smell

phase at room temperature

• The way a substance reflects light
• the study of matter and the changes it undergoes

density

• a measure of the tendency of a chemical compound to maintain its original chemical composition rather than break down to form a different chemical
• refers to the temperature at which the solid and liquid states are in equilibrium - the terms are interchangeable and correspond to the same temperature; how the terms are applied depends upon the state the substance is in originally
• is a measure of how much the volume of matter decreases under pressure
• Mass per unit volume

melting or freezing point

• a measure of how much heat energy is needed to increase the temperature of a substance
• solid, liquid, gas or plasma at room temperature
• refers to the temperature at which the solid and liquid states are in equilibrium - the terms are interchangeable and correspond to the same temperature; how the terms are applied depends upon the state the substance is in originally
• a measure of the tendency of a chemical compound to maintain its original chemical composition rather than break down to form a different chemical

boiling point

• a measure of the tendency of a chemical compound to maintain its original chemical composition rather than break down to form a different chemical
• A characteristic of a pure substance that describes its ability to change into different substances
• the temperature at which a substance changes from a liquid to a gas
• is a measure of how much the volume of matter decreases under pressure
