When dripping water turns into icicles.
Are ALL of these properties of Solid, Liquid and Gas correct ?
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 the particles can over lap each other
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

Water vapour condenses and produces water droplets
The water is produced because of the cold
In the morning the water vapour is met by a colder air temperature.
It is going to be a sunny day
If you leave a pan of water boiling on the stove what will eventually happen to all of the water and why ?
By increasing the temperature of the liquid we will change its state of matter to a gas through evaporation.
the particles are cold enough to turn unti a gas such as steam
the particles have enough kinetic energy to break away from the liquid and diffuse in the surrounding air particles
the water starts to disappear into a gas
