When a parcel of air of air is cooled to the temperature at which it is saturated it has reached what?
When a paracel of air is cooled to the temperature at which it is saturated, it has reached its dew point.
What does a low dew point indicate about the moisture content of air?
The dewpoint is the temperature to which the air must be cooled to become saturated. A lower dewpoint, as in winter, indicates there is less moisture in the air, so the air must be cooled farther before it will become saturated with water. Dewpoint is a combination of many factors, including temperature, humidity, and pressure.
What 2 things affect air pressure?
Altitude , weather systems and gravity.Gravity is the reason of the air pressure , of course this is not noticed as the gravity is affecting every where. Also in terms of wind, heat is a major factor due to the varying temperature of night and day, and the fact that gasses tend to 'expand' when heated and 'shrink' when cooled.
What happens to air pressure when air is cooled?
When air is cooled the molecules move more slowly and they take up less room. The amount of space the air takes up shrinks which reduces the air pressure.
What can cause water vapor in the air to be cooled?
The process is called condensation. It occurs when the water is cooled below its boiling point due to the temperature in the environment cooling it.
What is the temperature to whicha ir must be cooled at and constant pressure to reach saturation?

What happens to volume when air temperature increases?
If pressure remains constant, then volume is directly proportional to temperature. Hot air is quite loud.
What is an explaination of briefly porous plug experiment?
In a porous plug experiment, a porous material acts as a barrier between two regions of different concentrations, allowing for the diffusion of molecules through the plug. By measuring the rate of diffusion, one can study the factors influencing diffusion, such as concentration gradient and material properties. This experiment is commonly used in studying diffusion processes in gases and liquids.
What is the volume of the gas before and after cooled?
The volume of a gas - at constant pressure - is proportional to the absolute temperature, that is, to the temperature expressed in Kelvin. This relationship is only approximate for real gases, but it is close enough for most practical purposes.
A sample of Xenon gas at 20degree Celsius and 0.570 ATM is cooled to a pressure of 0.100 ATM If the volume remains constant What is the final Celsius temperature?
It would be -221.7 deg C.
Why does temperature affect the air pressure?
Air temperature and air pressure are inversely proportional. As temperature increases, air pressure decreases. This is best demonstrated in an enclosed vessel.
A gas is measured at room temperature 24 deg C and is found to have a pressure of 100.0 kPa What is the new pressure if the gas is cooled to standard temperature O K?
LESS
What are the two major characteristics that change when air is heated and cooled?
Since we are talking abut heating and cooling - we define those both as changing the temperature so that is one characteristic. Other characteristics depend on how the heating and cooling occur. If the pressure remains the same, air will expand on heating and contract on cooling. If the volume is held constant, the pressure will increase with heating and decrease with cooling. The internal energy depends on what you do with pressure, work and heat. You can actually get a warmer gas with less internal energy and a cooler gas with more internal energy.
If pressure is constant how does a change in temperature affect the volume of a gas?
Pressure will rise as it is heated and lower as it is cooled according to Gay-Lussac's law.See link below for more information. The pressure will go up. An easy way to remember this is PTV. P for pressure, T for temperature, and V for volume. Write this on a piece of paper. Put you finger on whichever one is staying the same, and push up or down on the one that is changing, and the one you leave along will show you the change.
What is the most probable reason for the failure of the Boyle's Law experiment?
Have you used a Bicycle pump? Ever touched it after pumping up the tyre? It was hot.. Boyle's law works at a constant temperature so the equipment would have to be cooled to the original temperature.

Have you used a Bicycle pump? Ever touched it after pumping up the tyre? It was hot.. Boyle's law works at a constant temperature so the equipment would have to be cooled to the original temperature. At high temperatures (plasma state) it would fail. Have you used a Bicycle pump? Ever touched it after pumping up the tyre? It was hot..

Why does the pressure inside a cylinder fall when the temperature falls?
Gas expands when heated and shrinks when cooled. If the gas inside a closed cylinder is cooled, it will shrink, so it will push against the walls less. Therefore, less pressure.
