- Does matter change form?
- a Describes how substances can form new substances
- b If the property involves changing the substance to a different substance, it is NOT physical.
- c The process by which a gas changes its state to become a liquid
- d The process by which a solid becomes a liquid.

5 Multiple Choice Questions
- Boiling can occur only when a liquid reaches a certain temperature.
- The lowest temperature at which a substance begins to melt.
- Yes! The volume and shape changes NOT the density.
- The change of one substance into another substance
- The freezing point of a substance is the same at that substance's melting point. so at that particular temperature, the substance can exist as either a solid or a liquid.
5 True/False Questions
Example - A glass marble has a volume of 5cm cubed and a mass of 13g. What is the density of the glass? → D= mass/volume - 13g/5cm (cubed)
D= 2.6g/cm cubed
It will sink because the density of water is 1.0 g/cm cubed
What happens to the particles when condensation is occurring? → it melts
Why can't you identify a substance on the basis of density alone? → mass/volume
Describe the movement of particles in a liquid as it evaporates → Particles move fast enough to slide past one another
Signs of a chemical change? → The change of one substance into another substance
