Paper clips, magnets, whiteboard, tacks, desks (other answers may be accepted).
200
What are the major differences between a mixture and a solution?
A solution has two or more substances that are evenly mixed (one has dissolved) and are not easily separated.
200
When two or more substances combine to create a whole new substance.
What is a chemical reaction?
200
How do substances change state?
By changing temperature.
300
The ability to dissolve (break down into tiny pieces) in water.
What is solubility?
300
Why might a cup filled with ice cubes lose mass as the ice cubes melt?
As the ice melts, mass is lost from the cup as water is evaporated.
300
In a solution of coffee and sugar, describe which substance would be the solute and which would be the solvent.
Sugar- Solute
Coffee- Solvent
300
Is ice melting a chemical or physical change? Why?
It is a physical change because a new substance is not being created. Ice is just frozen water. When it melts, it is still water.
300
Describe the major difference between a solid and a liquid.
A solid has a definite shape, but a liquid takes the shape of the container it's in.
400
