Are ALL of these properties of Solid, Liquid and Gas correct ?

• Yes

• No

Why can a liquid flow ?

• because it is in a random order

• because its particles move around, sliding over each other

• because it is a liquid

• because it is light weight

Why can a gas be compressed ?

• because its particles are far apart and have space to move into.

• because of their random arrangment

When we make ice-cream, or put something into the freezer, how are we changing its matter ?

• we are changing any of the liquid matter into solid matter

• by making it cold

• we are reducing its temperature

• we are changing any of the liquid matter into gas

When using salt grit on the pavements, what are we doing to make the snow melt ?

• changing the state of the snow from solid to liquid

• changing the snow to gas

• reducing the melting point of the ice so that it will melt.

• increasing the melting point of the ice and making it disappear
