Why do you need the freezer turned on to make Ice?
Ice will only form from water once water is cooled to below 0 degrees Centigrade. A freezer requires energy (ie it needs to be turned on) in order to pump heat out of the freezing compartment to lower the temperature in this compartment to below 0 degrees Centigrade. If the freezer is not turned on the temperature in the freezing compartment will be that of the room in which the freezer is kept.
Particles vibrate faster when they are cooled?
Particles vibrate faster when they are heated.
What happens to the particles of a liquid that is cooled until it freezes?
ereee
When a liquid or gas is heated the particles move?
When anything is cooled its particles move more slowly.
What happens to volume when air temperature increases?
If pressure remains constant, then volume is directly proportional to temperature. Hot air is quite loud.
Why freezer compartment is often located at the top of a refrigerator?
The freezer compartment is often located at the top of a refrigerator because warm air is less dense than cold air. The cooled air from the freezer compartment goes down, thus it is not lost.

When metal is cooled by ice what will the particles do?
The particles will contract.
How can a object cool?
an object can be cooled by air or by a fridge or freezer.
When a liquid is cooled its particles what?
colder

Particles vibrate faster when they are heated.
Why is a freezer compartment at the top of a refrigerator?
The cooling element in freezers is at the top in order to keep it its coolest. This is because in a freezer or fridge the heat travels using thermal convection. In your kettle you have a the heating element at the bottom so the water particles are less dense and rise upwards beofore cooling at the top and becoming colder denser particles that then replace thehot particles at the bottom. This cycle carries on....however in a fridge or freezer you want the particles to be colder and denser so the cooling element is at the top so it allows the particles rise then to cool faster at the top. Its basically the reverse of what you have in your kettle, that allows you to boil your water!
What happens to particles in a substance when its heated or cooled?
In a solid, the particles start to vibrate a lot.In a liquid, the particles begin to move around faster and faster.In a gas, the particles move extremely fast through the air.
Why does your freezer mist when opening door?
When the freezer door is closed the freezer freezes all the water vapour that is in the air inside the freezer compartment. First the invisible molecules of water vapour in the air condense into tiny water droplets, making a mist. Then those droplets freeze solid at 0oC.When the freezer door is opened, the new air from outside has invisible water vapour in it, so the coldness from inside the freezer makes the invisible molecules in the new air condense, thus forming a mist of tiny water droplets suspended in the air.So opening the freezer lets the cold air from inside the freezer cool and condense the water molecules that are in the air just outside the freezer. The result is the mist that you see, a swirling mini-cloud of tiny water droplets suspended in the cooled air.Some of this mist will go on to the cold surfaces inside the freezer compartment, where they will freeze solid when the door is closed.Most people don't want too much ice in the freezer compartment, so it is best to not open the freezer door too often. And then make sure that it is closed quickly afterwards, otherwise a lot of ice will build up in the freezer compartment and it will become more difficult to remove the frozen food.
When a liquid is cooled its particles become a?
colder
Can you put couscous in the freezer?
Yes, couscous with vegetables can be safely frozen.
What happens to particles when cooled?
it loses energy that makes it not move as quickly, therefore it gets smaller. that answer your question?
