Why does density increase when a gas is compressed?
There will be the same amount of gas but in a smaller space. Density is mass/volume So as volume decreases and mass is constant, the density increases.
How does increasing the density of a gas affect air pressure?
The increase in pressure signifies the increase in the number of collisions of the gas atoms with its container, this can result from 2 factors (when temperature is constant): either there is gas added, or the volume of the container has been decreased. Thus the Density, which is mass (which can be equated to amount of gas) divided by volume, and increase in mass or decrease in volume will effectively increase the density of the gas.
How do you change the mass or volume of a gas in order to decrease the density?
- modifying the temperature- modifying the pressure- modifying the volume
What happens to a gas when you add thermal energy?
In this case the volume increase, the density is lower.
What happens to gas when you add thermal energy?
In this case the volume increase, the density is lower.
How does increasing the density of gas affect its pressure?
By increasing the density of a gas its air pressure will subsequently increase.
What happens the density of a gas as it is compressed?
The atoms or molecules of a gas will increase in thermal energy when the gas is compressed. The kinetic energy of those atoms or molecules will increase as they are forced closer together in compression, and the temperature of the gas will increase.
What is a result to increasing the temperature of a gas?
In a closed system the pressure increase. In other conditions the volume increase and the density decrease.
If chlorine gas is compressed does its density increase?
Yes It does increase. http://webbook.nist.gov/chemistry/fluid/ While this website doesn't include chlorine, any gas that is compressed will increase in density. Different gasses all have different compression-density relationships, but all gasses that are compressed will increase in density.
Can a increase in density result from an increase in mass and no change in volume?
Yes. Density is mass/volume so if mass increases so does density if volume does not change
Do you need great pressure change to have a measurable change density in gases?
Density = mass / volume, so to change density you need to change the mass within a fixed volume or the volume of a fixed mass. Increasing the mass or decreasing the volume will increase the pressure by a linear degree, so no, the density of a gas is very easy to change. E.G.: Decreasing the volume by 1.0% will increase the density by 1.1%. Increasing the mass by 1.0% will increase the density by 1.0%.
How to calculate the density of a gas?
To calculate the density of a gas, you need to know the gas's mass and volume. The formula for density is density mass/volume. Measure the mass of the gas using a scale and the volume using a graduated cylinder or other measuring tool. Then, divide the mass by the volume to find the density of the gas.
