How does the expansion of air affect temperature?
It cools.
What happens to air when after repeated compression and expansion?
Nothing much. Compression heats it up, expansion cools it down. Unless the machine that does the compressing and expanding add something, it'll stay exactly the same.
What is determined by how magma cools and where it cools?
Its texture.
What happened to lava when it cools?
Extrusive igneous rock is formed from the crystallization of minerals as the lava cools.
When liquid rock cools slowly will crystals be bigger or smaller then when it cools fast?
bigger
How does the expansion of air affect temperature?
It cools.
Matter expands when it gets hotter and contracts when it cools?
The explanation of Thermal Expansion.
What happens to air temperature when it is compressed or allowed to expand?
Heats with compression, cools with expansion.
What are examples of thermal expansion and contraction?
the Mercury in a thermometer expands when heated and contracts when the temperature cools down.
How do themometers work?
by the metallic coeffeictent of expansion of mercury. When mercury gets warmer it "spreads out" (expands) when it cools it "shrinks".
Why does copper shrink when it cools?
Copper shrinks when it cool because of Thermal Expansion. Sources: It was a question in my science book, and I got the question right. P.S. Would you like to know what Thermal Expansion is?
What is Transpiration Stream Theory?
It is the evaporation of water from the leaves and stems of the plant. It cools the plant and allows the diffusion of Co2 from the air for photosynthesis.
What happens to air when after repeated compression and expansion?
Nothing much. Compression heats it up, expansion cools it down. Unless the machine that does the compressing and expanding add something, it'll stay exactly the same.
How is the expansion of rock important in the for formation of lava?
Because when lava cools out it will turn into rock and some roks have small animal fossils in them too.
What happens when the Bimetallic Strip cools down?
When the bimetallic strip cools down, the metals in the strip contract at different rates due to their varying coefficients of thermal expansion. This differential contraction causes the strip to bend, with the side of the metal with higher expansion coefficient (usually the inner layer) being on the inside of the curve.
What is an expansion joint in construction?
An "expansion joint" is a joint left in between sections of the same material, like concrete or steel, that allows movement as the material heats up or cools down. Without it, concrete, for example, can expand and crack in hot temperature.
How do you install an air chamber on your paintball gun?
An expansion chamber is screwed into the location typically occupied by the regulator, and are most commonly used for co2. They are less effective than regulators, as they only allow the co2 to expand instead of actively regulating the pressure.
