when two or more substances combine and form new substances flammability a substance’s ability to catch fire
Chemical Reaction
is a property that allows you to identify a substance
Characteristic Property
of a substance is the temperature at which a liquid substance changes to a gas
Boiling Point
Is sugar soluble in water?
Yes
Give 2 Examples of chemical properties
flammability and reactivity
of a substance refers to its ability to be flattened and/or rolled into thin sheets
Malleability
is the tendency of a substance to undergo a chemical change by reacting by itself or with other substances to form new substances
Reactivity
are those properties which can be observed without altering the material
Physical properties
True or false?
Copper is an example of a ductile substance.
True
For many gaseous solutes, as the temperature increases, solubility does what?
Decreases
is a measure of a substance’s ability to conduct heat or electricity
Conductivity
a substance does not dissolve in solution
Insoluble
of a substance is the temperature at which a solid substance changes to a liquid
Melting Point
You have a coin with a volume of 10cm3 and a mass of 50g. What is the density of the coin?
Density is 5g/cm3
What do you do if you want to smell a chemical?
Waft it towards your nose
a substance is determined by how much of a solute will dissolve in a solvent
Solubility
is the ability of a substance to be drawn into a wire
Ductility
are those which become evident during or after a chemical reaction
Chemical properties
For many (but not all) solid solutes, as the temperature increases, solubility does what?
Increases
What is the formula for density?
Density=mass/volume
the strength in tension or pulling force
Tensile strength
of a substance is a measure of the compactness of its particles, which is quantified by its mass per unit volume
Density
Water is known as?
the universal solvent
