Greater pressure on a gas will compact the gas into a smaller volume. If the compressed gas is then warmed, it will try to expand, and the pressure the gas exerts on the container will increase. If the pressure becomes greater than the container can hold, the container will explode or split and the excess gas pressure released.
the molecules are stricking a larger area with the same force
At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.
By increasing the volume of a gas, at the same temperature, the gas molecules are applying the same force over a larger area. Because pressure = force divided by area, the pressure decreases.
This is a consequence of Boyle-Mariotte law: pV=k. at constant temperature.
true
as the pressure decreases the volume of gas increases at constant temperature
As the pressure increases, the volume wil decrease.
decrease
Yes. Since pressure and volume are inversely related, volume decreases when pressure increases (as long as temperature is constant). Consider the equation: PV=nRT, where n = moles, T is in degrees Kelvin, and R is the gas constant 0.082. Do the algebra and see how: P=nRT/V and the inverses become more easily understood.
A sample of gas occupies 1.55L at STP. What will the volume be if the pressure is increased to 50 atm while the temperature remains constant?
Volume & pressure are inversely proportionate, if temperature stays constant volume would decrease at a factor proporionate to the increase in pressure.
In a closed system with constant pressure and no input or output of heat, the gas temperature will remain constant. In that same system, if the pressure is increased, then the gas temperature will also increase. If pressure is decreased, then the gas temperature will decrease.
As pressure increases, if temperature is constant, the gas will decrease in volume.
Pressure and temperature will decrease
As pressure increases, if temperature is constant, the gas will decrease in volume.
At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.
A loss of gas, or a decrease in temperature.
Temperature increases as pressure increases.
as the pressure decreases the volume of gas increases at constant temperature
since PV=nRT and we assume that the number of moles and temperature remains constant, we can assume that PV=R as R the gas constant will not change, if pressure is increased, then volume must decrease to counteract the change in pressure
Increase pressure: decrease volume, increase temperature, increase moles of substance. Decrease pressure: do the reverse
Pressure will decrease with (because it is inversely proportianal to) volume, if (and only if!) temperature is held constant.
