If the volume of a fixed amount of gas at constant temperature decreases its pressure does what?

Volume and pressure vary indirectly, which means that when one goes up, the other goes down. If the pressure goes up, the volume goes down. If the volume goes up, the pressure goes down.
Mathematically:
P1V1 = P2V2
The left side represents the beginning conditions, and the right side represents the pressure and temperature that have changed. Note that this formula assumes constant mass and temperature.

The volume of air in a balloon decreases as soon as it is taken out of the warm store and into the cold air This is due to?
System volume of a gas is directly related to pressure, volume, amount of molecules, and the gas constant. When the balloon is moved to cooler air it loses heat. The loss in temperature results in a contraction of volume.
How does compressing a gas affect volume?
Compressing a gas means increasing the pressure on the gas and according to Boyle's law pressure is inversely proportional to the volume of a given amount of a gas(at constant temperature) . Therefore increasing the pressure (compression) of the gas reduces the volume of the gas.
What is happening to a parcel of air when the dew point decreases if th amount of water vapor remains constant?
As the dew point decreases, the water vapor remains constant because the dew point doesn't interfer with the water vapor.
Which two properties characterize an air mass?
Density Specific Volume Pressure Temperature Viscoisy Gas Constant Heat Specific
As the dew point temperature of a sample air decrease the amount of moisture in that saple of air?
The moisture decreases.
When the pressure on a gas increases at constant temperature its volume?
decreases
What happens to the pressure of a gas if the volume increases?
It will increase? No it will decrease when the same amount of gas is held at constant temperature.
When a container decreases in size what will happen to an amount of gas in the container?
Assuming the temperature stays constant and there is no leakage of gas, then if the container decreases in size then the pressure will increase.
How does deacresing the temperature affect the volume of a gas?
If the amount of gas and the pressure remain constant, the volume will decrease by 1/273rd the original volume for each degree Celsius that the temperature decreases.
How are pressure volume and temperature of gases related?
The temperature, pressure, and volume of gases can be related by the ideal gas equation. PV = nRT where P is pressure, V is volume, n is moles, R is that ideal gas constant, and T is the temperature in Kelvin.
What is the temperature if the gas pressure is constant?
At isobaric (pressure) expansion (volume increase) the temperature will increase because V is proportional to T for the same amount of gas (closed container) at constant pressure.
What does Charles' Law state?
In thermodynamics and physical chemistry, Charles's lawis a gas law and specific instance of the ideal gas law, which states that:At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature (in Kelvin) increases or decreases.
What is the assumption of Charles' law?
The volume of a given mass of gas at a constant pressure varies directly with its temperature. This means that, at constant pressures, the volume of a given mass of an ideal gas will increase or decrease by the same factor as its temperatures increases or decreases. For example, if 20 liters of a gas at 283 K was then raised to the temperature of 300 K, the volume would increase to 21.2 liters.Mathematically:V1 / T1 = V2 / T2
What is an inversely proportion in Boyle's law?
In Boyle's law, the volume of a given amount of gas is inversely proportional to its pressure, meaning that as the pressure increases, the volume of the gas decreases, and vice versa. Mathematically, this relationship is represented as PV = k, where P is the pressure, V is the volume, and k is a constant.
What happens when pressure falls and temperature rises?
Temperature is really just the amount of kinetic energy in the molecules of a substance. If you add more energy by heating the substance then the molecules dash about faster and faster. This increases the pressure if the substance is constrained, like gas in a jar or in a bomb.
What will you observe about the temperature of a fixed amount of air inside a rigid container if the pressure inside decreases?
it will decrease
At constant pressure if the temperature of a given amount of gas increases then the volume must do what?
increase
