Physical Properties
A property that can be observed or measured without forming a new substance.
What are physical properties?
Change of matter that usually results from pressure, temperature or motion that does not change the physical properties of the substance.
What is a physical change?
The properties that describe the reactivity of a substance with other substances.
What are chemical properties?
The description for a substance turning into a different substance.
What is a chemical change?
The relative density of something that floats on top of water.
What is less dense?
Solid, Liquid, Gas
What is state?
The three 'S's that we look for to indicate a physical change?
What are changes in Shape, State or Solution?
Describes substance's ability to participate in a chemical reaction (react with others)
What is a chemical property?
Heat or light given off or absorbed, starting material used up, colour change, gas bubbles forming, a precipitate forms in a liquid.
What are the five things that indicate a chemical change?
The relative density of something that sinks
What is more dense?
These can be used to make qualitative about a substance.
What are your five sense?
The term for how well a substance dissolves.
What is solubility?
Reactivity, Flammability, Toxicity
What are examples of chemical properties?
The evidence that digesting your food is a chemical change.
What is starting material used up and colour change?
Stays the same for all substances/objects no matter what the sample size and is characteristic of that substance. The amount of mass per unit volume.
What is density?
Physical property describing how bendy or moveable the substance is.
What is malleability?
The 'S' for when a piece of paper is crumpled.
What is a change in shape?
How likely something is to react with another substance.
What is reactivity.
The evidence that cooking an egg is a chemical change.
What are colour change, heat absorbed, irrreversible?
D = M / V
What is the equation for density?
Physical property describing something's ability to be pulled into wires.
What is ductility?
The boiling of water to produce steam.
What is a change in state?
The property that describes how likely something is to burn or ignite easily.
What is combustibility?
The evidence that vinegar reacting with baking soda is achemical change.
What are starting material used up, gas bubbles forming in a liquid?
g/mL or g/cm3
What are the Units for density?
