When the air near the freezer compartment is cooled does the energy of the air particles increase?
No, when the air near the freezer compartment is cooled, the energy of the air particles decreases. Cooling causes the particles to move more slowly, which results in lower kinetic energy. As a result, the temperature of the air drops, leading to denser and colder air in that area.

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?

When a liquid or gas is heated the particles move?
When anything is cooled its particles move more slowly.
Why do some substances change when they are heated or cooled?
When substances are heated or cooled, the energy of their particles changes. Heating causes particles to move faster and increase in energy, which can result in changes such as melting, vaporization, or chemical reactions. Cooling causes particles to slow down and lose energy, leading to changes like freezing or condensation. These processes are due to the rearrangement of particles and their interactions at the molecular level.
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.

How can a object cool?
an object can be cooled by air or by a fridge or freezer.
What happens to particles in a solid when they are heated or cooled?
When a solid is heated, the particles gain energy, leading to increased movement and vibration. This causes the particles to expand, leading to an increase in volume. Conversely, when a solid is cooled, the particles lose energy, resulting in decreased movement and contraction, which decreases the volume of the solid.
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!
When a liquid is cooled its particles what?
colder
Can you put couscous in the freezer?
Yes, couscous with vegetables can be safely frozen.
What happens to matter when it is heated or cooled?
When matter is heated, its particles gain energy and move more rapidly, leading to an increase in temperature and expansion of the material. Conversely, when matter is cooled, its particles lose energy and move more slowly, causing a decrease in temperature and contraction of the material.
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.
What happens to the density if an object is cooled?
If an object is cooled, the particles within the object will lose kinetic energy and move closer together. This results in an increase in the density of the object because the same mass is now packed into a smaller volume.
When a liquid is cooled its particles become a?
colder
What happen to volume of substance when placed say in a freezer?
A number of factors have to be considered, the state of the substance, solid, gas or liquid. The condensation and freezing point of the substance. The temperature inside the freezer. The pressure Most, but not all, substances reduce in volume and increase in density when cooled. Water for instance, reduces in density when frozen.
