A 5 mL glass of water has a boiling point of 100 degrees Celcius. What would be the boiling point if the amount of sample is doubled? Hint : Boiling Point is intensive property
50 degrees Celsius
100 degrees Celsius
150 degrees Celsius
200 degrees Celsius
What is the definition of intensive property?
Properties that vary depending on the amount of matter
Properties that do not change with amount of matter

Which of the following statements tells us that a sample of liquid is pure water?
It is colourless.
It leaves no residue when filtered.
It boils at 100oC.
It is odourless.
this arrangement can be used to separate
mixture of sand and water
mixture of salt and water
ink components
chalk and water
A student placed a small chip of limestone into a hydrochloric acid solution, and carbon dioxide gas was released. The carbon dioxide provided evidence that
only a physical change occurred.
a chemical change occurred.
only a loss of mass occurred.
the formation of an element occurred.
Mixtures are different than pure substances because mixtures-
have lower boiling points
can be separated physically
are less dense than pure substances
contain only one type of atom
Which process represents a chemical change?
A lake freezes over into ice
Vinegar bubbles when baking soda is added
A metal bar is rolled into a flat sheet
Sand, water, and salt combine to form a mixture
A student investigates the properties of an unknown liquid substance in a beaker. The student finds the substance has a mass of 56.2 g and a volume of 42.3 mL. The liquid has a yellow, translucent appearance. The liquid has a freezing point of 13°C and a boiling point of 105°C. When the liquid boils, a white powder residue is left in the beaker.
What conclusion can the student make based on the evidence collected?
The substance is a pure substance because it has a density that remains constant.
The substance is a mixture because it has a yellow and translucent appearance.
The substance is a pure substance because it has a definite freezing point and boiling point.
The substance is a mixture because it left a white powder in the beaker when boiled.
