Is the mass diffusivity of air in water vapour equal to that of water vapour in air?
Wiki User
∙ 11y ago
No, the mass diffusivity of air in water vapor is different from the mass diffusivity of water vapor in air. The diffusivity of a substance in a medium depends on various factors such as temperature, pressure, and molecular weights of the substances involved, leading to different diffusion rates in different directions.

Does water vapour have mass?
Yes, water vapor does have mass. Water vapor is a gas composed of water molecules, and like all matter, it has mass. However, the mass of water vapor is much lighter compared to liquid water.
How does the mass of a floating object compared to the mass of the water displaced?
The mass of a floating object is equal to the mass of the water it displaces. This is known as Archimedes' principle, which states that the buoyant force acting on an object is equal to the weight of the fluid displaced.
How do you prove that the mass of a substance of a density is equal to the volume of water?
To prove that the mass of a substance is equal to the volume of water, you can use the principle of buoyancy. First, weigh the substance in air to determine its mass. Then, immerse the substance in water and measure the volume of water displaced. The mass of the water displaced is equal to the mass of the substance, thus proving the equality.
What is equal to the mass of kilogram?
A liter of water has approximately a mass of one kilogram.
What For an object to float the mass of the water displaced must the mass of the object?
For an object to float, the mass of the water displaced must be equal to the mass of the object. This is known as Archimedes' principle, which states that the buoyant force acting on an object is equal to the weight of the fluid displaced by the object. When these two masses are equal, the object will float.
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528
Relative humdity is a ratio of what?
The mass of water vapour in a given quantity of air to the maximum mass of water vapour that it could hold - at the specific temperature and pressure.
How does the mass diffusivity of a gas mixture changes with temperature and pressure?
The mass diffusivity of a gas mixture generally increases with temperature because higher temperatures lead to increased molecular velocities and therefore enhanced diffusion rates. Pressure can also have an effect; typically, an increase in pressure reduces the mass diffusivity due to the decrease in intermolecular space available for diffusion.

How will you show that air has mass?
There are many ways to prove air has mass. One of them is : Take some water in a closed vessel and heat it till all the water boils. As we know when there is no transfer of particles mass remains constant. Therefore, the mass of the water vapour (air) is equal to the mass of the water taken. Hence, it is proved that air has mass.
Does water vapour have mass?
Yes, water vapor does have mass. Water vapor is a gas composed of water molecules, and like all matter, it has mass. However, the mass of water vapor is much lighter compared to liquid water.
What refers to the amount of water vapour in the air?
Relative Humidity is the measure of water vapour in air. It is the ratio of the actual water vapour in air divided by the maximum amount the water the air can hold at the existing temperature and pressure. It tells how fast or slow the water on the body or in clothes will evaporate or in otherwords is the air dry or humid. Absolute measure of water vapour in air is called specific humidity. It can be measured as ratio of mass of water and mass of dry air.
What is specific humidity and relative humidity?
Specific humidity is the mass of water vapor present in a unit mass of air. It is expressed in grams of water vapor per kilogram of air. Relative humidity is the ratio of the amount of water vapor present in the air to the maximum amount of water vapor the air can hold at a given temperature, expressed as a percentage.
What is the physical significance of the thermal diffusivity and How is it defined and what?
Thermal diffusivity signifies the rate of heat transfer into the solid. If it is higher then less time is required for the heat to penetrate into the solid. it is th property of a solid. If we know the mass density,specific heat and thermal conductivity coefficient then we can determine its thermal diffusivity.
The ratio of thermal boundary layer thickness to the concentration boundary layer thickness is?
The ratio of thermal boundary layer thickness to the concentration boundary layer thickness is typically denoted as Prandtl Schmidt number (PrSc). It is defined as the ratio of thermal diffusivity to mass diffusivity of a fluid and represents the relative thicknesses of the thermal and concentration boundary layers in a flow field.
Does water vapour take up more space than the same mass of liquid water?
All gasses take more place than the same mass of its fluid or steady fase. Here: vapour is not a gas, it is consisted of very small fluid parts!
When methane burns carbon dioxide and water are formed The mass of carbon dioxide plus the mass of water equal the mass of the methane plus the mass of OXYGEN?
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
