Water exists in 3 states: Solid Ice, Liquid water, and Water Vapour.
What State it is in depends on the movement of its atoms.
The movement of its atoms depends on how much Thermal Energy the atoms have
How much thermal energy the atoms have on average, depends on the Temperature
Use the slider and add Thermal Energy
Look at what happens to the movement of the Atoms!
Goldilocks needs to melt ice into cold water
If she heats them for too long then she'll have hot water!
Step up to the challenge of the Goldilocks Meltdown
Before the three Bears arrive!
Water exists in 3 states: Solid Ice, Liquid water, and Water Vapour.
Ice can be heated from super cold to icy cold.
Water can be heated from cold to hot
Water vapour can be heated, like in a pressure cooker!
The amount of Thermal Energy required to heat water in each state is called it's heat capacity!
Heat capacity is how much energy 1 gram or 1 kg of a substance must absorb before its temperature will increase by 1 degree centigrade
Water exists in 3 states: Solid Ice, Liquid water, and Water Vapour.
You can Melt ice into Water
You can Vaporize water into water vapour
These state changes require MASSIVE amounts of energy.
The amount of energy required is called Latent heat
Latent heat of Fusion is the amount of energy required for a solid to liquid State change
Latent heat of Vaporizaiton is the amount of energy required for a liquid to gas State change
Water exists in 3 states: Solid Ice, Liquid water, and Water Vapour.
Have a look at how much energy it takes to
Heat ice
Melt ice
Heat water
Vapourize water
Heat water vapour
What do you notice about the quantity of energy required?
Think about it in terms of your experiences with ice, water and water vapour.
Water exists in 3 states: Solid Ice, Liquid water, and Water Vapour.
Press Start on the Simulation
Observe the movement of the atoms as more and more energy is added
Why do they move like that? What does it mean in terms of energy, state
Look at the graph, the Heating Curve. Why does it look like that?
When you heat things, you usually want to stop at a certain point.
Heat the ice a bit so people's hands don't freeze to it
Heat water to wash your face
Heat water more to make a coffee
Can you heat the water just right?
Play the game before it gets too hot!
You put massive pieces of Ice into your chillybin
You put small icecubes into your drink
Those massive pieces of ice will stay frozen for ages
The size of the icecube matters!
The bigger it is, the longer it will stay frozen
Air temperature matters
Eat an Iceblock in Winter, and it will stay frozen till the last bite
Eat an Iceblock at your New Years Day campsite, and it will melt down your arm before you finish.
The hotter the air temperature, the faster the ice will melt
Change how Massive the ice is.
Change the air temperature
