It means that if the gas is allowed to expand into a larger volume, the pressure - inside the container that contains the gas - will be less.
You can reduce the pressure of a gas by any of the following:* Reducing the amount of gas (letting some gas escape)
* Reducing the temperature
* Increasing the volume
It lowers the pressure.
A decrease in temperature
its VOLUME
1) Increase in heat 2)Decrease in volume
Yes, since when you open the bottle/can, the pressure decreases leading to a decrease in temperaure (albeit very slight). pV=nRT V,n and R remain constant so if the pressure is decreased, the temperature must also decrease.
its temp
Depends on the other conditions. If the volume remains constant, the density will remain the same (but the pressure will increase). If the pressure remains constant, the volume will increase - and therefore the density (mass / volume) will decrease.
decrease,because the cube of sugar absorb some heat
1) Increase in heat 2)Decrease in volume
A large DECREASE in the surface pressure will result in water turning to water vapor at room temperature.
from the gas laws and Charles 2nd law, it can be concluded that pressure is directly proportional to temperature..hence if the temp decreases; pressure also decreases as the kinetic energy of the molecules decreases; the collisions decrease hence pressure of the molecules inside the container decrease.
I always thought it to be the difference between 1. High pressure 2. Low pressure 3. Higher temp 4.lower temp and 5. Humidity, but then I am only a boiler maker.

Temperature, pressure, and common ion effect
Ammonia is a liquid at any temp,as long as it is in an contained vessel.The only change in ammonia, in a contained vessel ,is the internal pressure,due to the pressure-tempature relationship.Anhydrous ammonia is a 99.95% pure liquid for Refridgeration grade.Ammonium Hydroxide is cleaning solution grade,with ammonia only being 10-30% by volume.Out of a contained vessel,ammonia boils at -28 degrees and rapidly evaporates.
actually it does. The lower the temp. the lower the air pressure so high temp cause high pressure.
Warm temp create area of low atmospheric pressure on the Earth's surface while area of high pressure r generated when temp r relatively cold. Once established, the thermal gradient then develops a flow of air that goes from high 2 low pressure
yes temp does affect the strength of magnets. The cooler the magnet the stronger it gets.
work on a simple principle that the ability of air to hold moistre decrease with decrease in temp.
Air doesn't effect the bounce of the ball much higher air pressure the harder the ball lower pressure softer the ball temp effects it too colder soft warmer harder
