Moist air is less dense than dry air at the same temperature and barometric pressure. Which is the best explanation for this observation?

Is ammonia more dense or less dense than air?

Is moist air heavier than dry air? Explain.

The velocity of sound in dry air is V_(d) , and in moist air it is V_(m) . The velocities are measured under the same conditions of temperature and pressure. Which of the following statements is fully correct?

Why dry air is heavier than moist air?

Why dry air is heavier than moist air?

Why dry air is heavier than moist air?

A cycle tube will burst if the volume of air inside exceeds 1L at the room temperature. If at 1 bar pressure the air occupies 500 mL, then up to what pressure can the tube be expanded at the same temperature ?

A glass tumbler containing 243 mL of air at 100 k Pa and 20^(@)C is tuned upside down and immersed in a water bath to a depth of 20.5 metre. The air in the glass is compressed by the weight of water above it. Calculate the volume of air in the glass assuming the temperature and the barometric pressure have not changed.
