Random Trivia
This is the newest AFL team, established in 2010.
What is Greater Western Sydney?
A substance is called this, when it can be dissolved in water like salt or sugar.
What is soluble?
This is the state of matter for helium.
What is gas?
This phase change occurs to water cooling down below 0 degrees celsius.
What is freezing?
This type of mixture forms when a soluble substance like salt dissolves in water and is mixed.
What is a solution?
This is the substance in a solution that dissolves the solute, often a liquid like water.
What is solvent?
This separation technique separates solids from other solids based on the particle size.
What is sieving?
This technique separates mixtures based on whether they are magnetic like iron and nickel, or non-magnetic like paper and aluminium.
What is magnetic separation?
This is the number of bases in baseball.
What is four?
A solution that has a small amount of solute dissolved is described this way.
Bonus: Describe the colour of this type of solution.
What is dilute?
Bonus: light coloured.
Mercury is a weird metal because it is in this state of matter at room temperature.
What is liquid?
Water vapour does this when it cools down, on the side of a cool glass.
What is condense/condensation?
This type of mixture contains an insoluble substance in a liquid, which easily settles over time.
What are suspensions?
In a soft drink, these substances are sugar, colouring, carbon dioxide and others.
What is the solute?
Evaporation, crystallisation and distillation are three separation techniques that separate based on boiling point.
This separation technique separates solid solutes from solutions.
What is crystallisation?
This technique manually separates based on colour, size, or shape. It has historically been used by Aboriginal peoples to identify the lighter colour, smaller eucalyptus leaves for a more effective medicine.
What is handpicking?
This is the number of runs a person has in cricket, if they're out for a duck.
What is zero?
This feature of gases means that they can be pushed into a smaller volume/space by applying pressure.
What is compressible?
This property means that 200mL of juice in a juice box remains 200mL when poured into a cup.
Bonus: which states of matter exhibits the same property?
What is fixed volume?
Bonus: Solid and liquid.
Carbon dioxide, or dry ice, does this as it heats up.
Unlike muddy water, this mixture containing an insoluble substance don't settle over time. They can also be made of liquids in gas. Two examples are hair gel and hand cream.
The ocean is this type of mixture, with this solute and this solvent.
Solute: salt
Solvent: water
Evaporation, crystallisation and distillation are three separation techniques that separate based on boiling point.
This separation technique separates the lower boiling point substance from the higher boiling point substance, because the lower boiling point substance moves through the condenser and cools down and is kept as a liquid.
What is distillation?
This separation technique separates substances of different densities by spinning the sample around very quickly.
What is centrifuging?
This is the name of the snow monster Elsa created to protect her ice castle.
What is Marshmallow?
This solution has the maximum amount of solute dissolved in it.
What is saturated?
This is a property of solids that means that a chair is the same inside and outside the classroom. (This is a two word response - fixed or variable, and the property)
What is fixed shape?
This phase change occurs for certain substances where a gas turns directly into a solid.
What is deposition?
This is a particular type of colloid which means the substances don't separate over time, but made of two or more liquids. Milk and mayonnaise are two examples.
What are emulsions?
Identify the solute, solvent and solution for a tea drink.
Bonus: considering the tea bag, what type of mixture is this?
Solute: colour, flavouring
Solvent: water
Solution: tea drink
Bonus: suspension
This separation technique separates medicinal substances from fresh plant material by heating it in cool fires. This was used by various Aboriginal peoples.
What is steam distillation?
This separation technique was used by different Aboriginal peoples by tossing a mixture of seeds and husks into the air. The wind would blow away less dense husks.
What is winnowing?
This character fears the tick tock from a crocodile that swallowed a clock.
Who is Captain Hook?
These are samples that only contain one type of substance, chemical or particle, like helium, carbon dioxide or graphite.
What are pure substances?
These three properties describe gas.
What is variable shape, variable volume and compressible?
These three phase changes occur when a substance gains energy.
What are melting, vaporisation and sublimation?
A snow dome would be this type of mixture, which contains small insoluble flecks of snow in a liquid.
What are suspensions?
Blood contains a number of solid cells mixed in with a liquid called plasma that contains proteins and carbon dioxide dissolved in water.
Blood is this type of mixture.
Bonus: Identify the solute, solvent and solution.
What is suspension?
Bonus: Solute - protein and carbon dioxide
Solvent - water
Solution - plasma
Filtration separates this type of mixture, based on particle size.
Bonus: This word refers to the solid that is kept in a filter.
What is suspension / insoluble solid and liquid?
Bonus: What is residue?
These five separation techniques separate based on density.
What are flotation, decantation, yandying, winnowing and centrifuging?
