What happens when an object is cooled?
For most substances, when it cools, the particles move a bit closer together, so the volume decreases.
In terms of its blackbody curve describe what happens as a red-hot glowing coal cools off?
As an object cools, then its peak will move to the left, ie lower frequency/longer wavelength (Wien's Law). The total area underneath will also decrease (Stefan's Law).
What happens to the particles when an object cools?
When an object cools, the particles' kinetic energy transfers back into potential energy, the particles slow down.
Why a gas cools when it expands at high pressure?
as preasure increase tempreture decrease
What happens to the particles in a object as it cools?
The vibrational energy of the atoms and molecules reduces.
The decrease in the volume of an object as it cools is called?
contraction. Compression is often used when an external force is being applied to reduce the volume of the object.
Why does the density of liquid increase as it cools?
As something cools down, the kinetic energy of its molecules decrease. This corresponds to a decrease in volume occupied of the substance, so the density decreases.
Does Aluminium's density change when cooled down?
Yes. While the mass will not change, the volume will decrease as the aluminium cools. Consequently the density will increase.

What happen to the volume and density of an air mass when it cools or warms?
it changes
As ice cools from 273 K to 263 K the average kinetic energy of its molecules?
decrease
What is it called When water cools into a cloud?
when water cools in a cloud? Condensation! :]
What is the process called when a gas cools to a liquid?
Condensation.When a gas cools to form a liquid it's called condensation
Taking heat out of the air will do what to the air temperature?
Removing heat from the air will lower its temperature.
