To determine the amount of LPG used to reach 6 Bar pressure in a 55 Cu Meter container, you need to know the temperature of the LPG as pressure and volume alone are not sufficient. The amount of LPG in kg can be calculated using the ideal gas law equation PV = nRT, where P is pressure, V is volume, n is the amount of substance in moles, R is the ideal gas constant, and T is the temperature in Kelvin.

What is kinetic vapour pressure?
Kinetic vapor pressure is the pressure exerted by vapor molecules when a liquid is in a closed container and some of the liquid has evaporated into the gas phase due to kinetic energy. It is different from the equilibrium vapor pressure, which is the pressure at which the rate of evaporation equals the rate of condensation.
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
Why the relative lowering of vapour pressure is independent of temperature?
Relative lowering of vapour pressure is function of pressure of pure liquid and pressure of solutions when you increase temperature both the values increase and compensate the increase value, According to the Raoult's law, Psolvent = Xsolvent Po where Psolvent is the vapour pressure of the liquid solution, Xsolvent is its mole fraction in the solution and Po is the pure vapour pressure.
What is the accurate definition of vapor pressure?
Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. Vapor pressure is also known as equilibrium vapor pressure.
The vapour pressure of pure water is 30mm the vapour pressure of 10 glucose solution?
The vapor pressure of a 10% glucose solution will be lower than that of pure water because the presence of the solute (glucose) lowers the vapor pressure of the solution compared to the pure solvent (water). The exact vapor pressure will depend on the concentration of the solution and the nature of the solute.
Why lid will move when water boiled?
When water is boiled, it creates steam which expands, creating pressure in the container. As the pressure increases, it pushes against the lid causing it to move or lift slightly to release some of the pressure and prevent the container from bursting.
Does the evaporation in the evaporation column influence the total pressure?
evaporation as such influence on the total pressure. evaporation occurs when the total pressure is greater than the surface molecules vapour pressure. as the rate of evaporation increases , more vapour will be there at the top, and then the new total pressure will become the sum of the earlier total pressure and vapour pressure of the vapour evaporated. hence total pressure increases.............
Does vapour pressure include the partial pressure of water vapour in the atmosphere during boiling process?
The partial pressure of water (vapor) is included in the total pressure of the atmosphere (air) when boiling.
What is the condition which occurs when the atmospheric pressure is equal to the vapour pressure?
boiling
Does a vapour keep its shape?
No. It expands to fill any container it's in. If you pump it out of one container and into a different one, it changes its shape to match the new container.
What would have more vapour pressure pure ice or sweet ice?
Both will have same vapour pressure as salt{NACL} would get trapped in ice and in solid iced state get seprated from pure ice crystals. so in case melting of ice in soln state pure water will have more vapour pressure but in solid state both will have same vapour pressure.
What is the unit of true vapour pressure?
The unit of true vapour pressure is typically expressed in millimeters of mercury (mmHg) or kilopascals (kPa).
What is kinetic vapour pressure?
Kinetic vapor pressure is the pressure exerted by vapor molecules when a liquid is in a closed container and some of the liquid has evaporated into the gas phase due to kinetic energy. It is different from the equilibrium vapor pressure, which is the pressure at which the rate of evaporation equals the rate of condensation.
