When temperature rises, air expands and gets lighter. When temperature falls, air compresses and gets heavier. One of the rules about air temperature is that warmer air rises and cooler air falls.

∙ 11y agoWhen any gas, such as air compresses it gets warmer. This is why when you see the weatherman say there is a high pressure system moving in, more than likely, the temps are going up as well.
This is why valleys tend to be warmer than the area around them. There is more pressure on the air, hence raising it's temperature ie. Death Valley.
Now on the other hand, if you have ever taken a can on compressed air such as the stuff to keep keyboards clean, and held the spray button down long enough, the can will almost get too cold to hold. This is the result of pressure going down.
It all works at the molecular level. This is the basic principle that air conditioners and refrigerators work.

∙ 8y agoAir inside a container (for example a ballon) expands when the temperature of the air increases. This is because the increase in temperature causes the air partials to have a greater energy, meaning they move with a greater velocity and as such exert more force on the walls of the container causing the container to expand. The opposite happens if temperature is decreased
When air expands, it cools down as it loses energy and temperature drops. When air contracts, it heats up as it compresses and gains energy, causing temperature to increase.

What three factors affect how much an object expands or contracts as its temperature changes?
The three factors are the: material properties (coefficient of thermal expansion), temperature change, and original dimensions of the object.
How do themometers work?
Thermometers work by measuring temperature using a temperature-sensitive component, like a liquid, gas, or a digital sensor. When the temperature changes, the component inside the thermometer expands or contracts, and this change is indicated on a scale as a temperature reading.
Why glass breaks due to temperature change?
Glass breaks due to temperature change because it expands and contracts at different rates throughout its structure. When exposed to high temperatures, the glass expands uniformly. However, when it cools down rapidly, such as when in contact with a cold surface or exposed to cold air, the outer layers cool and contract faster than the inner layers, causing stress and potential breakage.
How does Mercury within a thermometer change?
As the temperature increases, the mercury in the thermometer expands, causing it to rise in the tube. This expansion is due to the heat causing the molecules in the mercury to move faster and take up more space. Conversely, when the temperature decreases, the mercury contracts, causing it to lower in the tube.
What is define coefficient of area expansion?
The coefficient of area expansion measures the relative change in area of a material with respect to a change in temperature. It is a material property that quantifies how much a material expands or contracts as the temperature changes. It is denoted by the symbol α.
When air expands of contracts what type of temperature change does it experience?
adiabatic
What is the thermometric property used in a mercury thermometer?
Not just a property of liquid but of all matter. All matter expands when heated and contracts when cooled, in thermometers the liquid, usually an alcohol, expands when heated lengthening the little line.

Does plastic exspnd to temter changs?
Yes. Plastics don't have as large a size change in response to temperature changes as metals do, but everything expands and contracts at least a little.

What change takes place in the liquid inside a thermometer when the thermometer is placed into something cold?
The liquid in thermometers contracts when placed in something cold (and expands when placed in something hot.)
Why glass breaks due to temperature change?
Glass breaks due to temperature change because it expands and contracts at different rates throughout its structure. When exposed to high temperatures, the glass expands uniformly. However, when it cools down rapidly, such as when in contact with a cold surface or exposed to cold air, the outer layers cool and contract faster than the inner layers, causing stress and potential breakage.
Is hot glass cracking when placed in cold water a chemical or physical change?
Physical. The glass expands or contracts depending on temperature, when you put a hot glass into cold water part of the glass cools and contracts while some of it is still in it's hot, expanded state.
How long does take thermal expansion take?
You may need to rephrase the question. Thermal expansion is the amount a material expands or contracts under temperature change; expansion is instantaeous with temperature. When temperature is reached, so is expansion. It may take time to rach temperature, however.
Can alcohol percent change because of different temperatures?
Yes, the alcohol percentage of a liquid can change with temperature because temperature affects the volume of the liquid. As temperature increases, the volume expands, leading to a decrease in alcohol concentration in the liquid. Conversely, as temperature decreases, the volume contracts, causing an increase in alcohol concentration.
