The little 3 in the air beside m would indicate cubic meters. A little 3 in the air beside cm would indicate cubic centimeters.
liters (volume)
Volume,Temperature and height above earth's surface
Yes, mm Hg (millimeters of mercury) is a unit of air pressure commonly used in barometric pressure measurements. Milliliters (mL), on the other hand, is a unit of volume and is not used to measure air pressure.
No, hot air does not weigh more than cold air. In general, air at different temperatures still has the same mass per unit volume, or density. The weight of a given volume of air depends more on its mass and not on its temperature.
Iron has the greatest density, followed by granite, water, and then dry air. Density is the mass per unit volume of a substance, and iron has a higher mass per unit volume compared to granite, water, and dry air.
i can find the mass of the air by comparing the volume of unit vaccum (ie)1 unit of course with the 1 unit of volume of air and then can find its density by examining the intramolecular force in the air particles and then by formula, density= mass/volume its simple
A "unit of area" has no mass (it has no volume).
Cubic meters
Raise it to the power of minus one. Specific volume is volume per unit mass, density is mass per unit volume. They are multiplicative inverses of one another.
The mass of a given volume of air depends on its density. Density is defined as mass per unit volume. To calculate the mass of a volume of air, you would need to multiply the density of air by the volume of air you are considering.
liters (volume)
The unit used to quantify the volume of air in a propane tank is typically measured in liters or cubic meters.
cubic meters, m3
Humidity means amount of water vapour present in air with respect to total amount of air. Relative humidity means ratio of amount of water vapours per unit volume of air to the capacity of air to held maximum water vapours in unit volume of air, at given air temperature.
Air pressure is the weight of all the air above you. The higher you go, the more air is below you.
