What happens to the density of a gas when the temperature is increased at constant pressure?

As the gas warms it will want to expand and as the pressure is constant it is being allowed to do so. This means that the same number of molecules (the original mass) is/are now taking up a bigger volume and as density is a measure of mass over volume ie:-
Density = Mass/volume
it is obvious what the density will do because the mass is constant and the volume is increasing.
Mass = 10
Volume 1 = 20
Volume 2 = 40
State 1 Mass/Volume 1 = 10/20 = density 0.5
State 2 Mass/Volume 2 = 10/40 = density 0.25

∙ 12y agoAccording to Charles' Law:
Volume of a gas increases as temperature inceases. But if the gas is contained in a rigid container then the volumme cannot increase, but the pressure will.

∙ 10y agoIf temperature increases at a constant pressure the volume will increase. Temperature and volume both stick together T-V --->(DOWN)

Wiki User
∙ 12y agoIt increases in volume due to the fact that the molecules spread farther apart.
Wiki User
∙ 13y agoVolume and temperature are directly proportional to each other and so when temperature is increased the volume also increase and vise virsa

The volume of a given mass of an ideal gas at constant pressure is?
directly proportional to the Kelvin temperature
What usually happens in general for a gas at a constant volume?
The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.
How do you find out the molar mass of a gas given density temperature and pressure?
MolarMass = [density x gas constant x temperature(in kelvin)] / pressure (in atm)
In a closed containerwhat effects does pressure have on a gas volume and density?
The gas pressure in a closed container increases with volume and increased temperature. Likewise, the pressure will decrease with decreased temperature.
What has a effect on water density?
Density of a liquid is indirectly proportional to the temperature. When the temperature raises, the density of the liquid decreases. Therefor the temperature has an effect on water density.
How does the number of particles affect the pressure of a gas?
Increased density and temperature.
How deos this change in volume affect the density of solids liquids and gasses?
A change in volume with a constant, unchanging Pressure and Temperature results in increased or decreased density, inversely dependent on increase or decrease in volume.
Is the density of gas similar to that of a liquid?
No, a pure liquid at normal temperature has a constant density while the density of a gas depends upon temperature and pressure.
What is the formula of density of air at particular Temp?
from the equation of state pressure = density * gas constant * temperature
What are the effects of temperature and volume of gas samples at constant pressure?
If the volume is constant, the density does not change with temperature. With increasing temperature there is still the same number of molecules confined to the same volume of space, so no difference in density.
If material is heated and expands the density of the material will?
This relies on 3 things. The Pressure, volume and temperature of a Gas is all related. If the pressure is kept the same and temperature increased. The Volume (of the container) must be increased. If the Volume (of the container) is kept constant and temperature is increased the Pressure will increase. A rough idea of what will happen can be worked out by, pV=cT Where p is the pressure, V is the volume of the container, c is a constant, T is the temperature.

Is lower temperature air is more dense?
No, density will be the same when cooling in a fixed container (pressure will drop, mass and volume unchanged)Yes, density will increase in an flexible balloon (volumewill decrease, mass and presure constant)Yes, density will be increased in cooler open air (increased mass in the same volume).
How do you find out the molar mass of a gas given density temperature and pressure?
MolarMass = [density x gas constant x temperature(in kelvin)] / pressure (in atm)
What are the properties of mass?
Density Specific Volume Pressure Temperature Viscoisy Gas Constant Heat Specific
How temperature affect the speed of sound?
The speed of sound in air changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure).Statement: The static air pressure p_ and the density ρ of air (air density) are proportional at the same temperature, because the ratio p_ / ρ is always constant, on a high mountain or even on sea level altitude.Notice: The ratio p_ / ρ (static air pressure to air density) is really always constant.
