The bromine vapors are heavier than air.
Yes
Yes
yes
Bottled LPG is heavier than air That why it is recommended to place the gas bottle outside of the cabin. Any gas leaks from the bottle being inside, would collect in the bottom of the boat causing a very explosive mixture
Yes, chlorine gas is about 2.5 times heavier than air. At standard conditions (pressure = 101.325 kPa and tenmperature = 15 degC), the density of chlorine gas is 3.04 kg/m3 and the density of air in 1.202 kg/m3. This means that chlorine gas will not 'rise' and tend to stay low on the ground. This causes many problems with ventilation.
Bromine exists as a diatomic gas. Thus, there are two moles of bromine atoms in 1 mole of bromine gas.
What has occured is a process called diffusion, which is the spreading of particles from a higher concentration to a lower concentration. The particles in any gas move quicly and in all directions and fill their container because there are no bonds between them. The jar with the bromine gas has a higher concentration of the gas particles, they move through the air particles to the jar with the lower concentration of bromine gas until they are dispersed evenly throughout the jar, hence the gas can be seen filling both jars. The same would happen with a clear gas but bromine is used for demonstration purposes as it has a colour and so the process can be seen clearly.
Is natural gas heavier than air
Gas is heavier than oxygen. Cold air is heavir than hot air
Natural gas is lighter than air and rises.
Yes LPG in gas phase is heavier than Air.
yes
This depends on the gas.
Bottled LPG is heavier than air That why it is recommended to place the gas bottle outside of the cabin. Any gas leaks from the bottle being inside, would collect in the bottom of the boat causing a very explosive mixture
Some are heavier, but some are lighter. For example, methane rises but propane sinks.
Chlorine is about 2.7 times denser than air.
No. Radon is a dense gas.
2.5 times
Argon, krypton, xenon, radon are denser than air.
