Is water vapor more or less dense than dinitrogen under the same conditions of temperature and pressure?
Water vapor is less dense than dinitrogen under the same conditions of temperature and pressure because the molecular weight of water vapor is lower than that of dinitrogen. This difference in molecular weight means that water vapor has fewer molecules present in a given volume compared to dinitrogen, resulting in lower density.
Does PRESSURE in a propane tank without propane have any weight?
Very little. When using propane the liquid is constantly being converted to the vapor that is used. When the liquid that weighs $.24 pounds per gallon is gone the vapor will last only a short time.
Do steam and water vapour have mass?
Yes it dose. Its just not very dense. If you boil water and can some how capture the steam the weight it the total weight of the steam and water that is left will have the same weight as the water you started with. (Mass can not be created or Destroyed)
What is difference between vapor pressure and vapor density?
Vapor pressure is the pressure exerted by a vapor in equilibrium with its condensed phase (liquid or solid) at a given temperature. Vapor density, on the other hand, is the mass of a vapor per unit volume of air. In essence, vapor pressure relates to the equilibrium between the vapor and its condensed phase, while vapor density pertains to the mass of vapor in a given volume of air.
What is the function of mercurial barometer?
A mercurial barometer measures atmospheric pressure by using a column of mercury in a glass tube. As air pressure changes, the level of mercury in the tube rises or falls, indicating the current atmospheric pressure. This information is used to provide weather forecasts and monitor changes in barometric pressure.
