    Explain why sound travels faster in warm air than in cool air.

    STATEMENT-1 : Wet air is heavier than dry air. STATEMENT-2 : The density of dry air is less than the density of water at 1 atm and 273K.

    Assertion: Wet air is heavier than dry air. Reason: The density of the dry air is more than density of water.

    The density of air is 0.00130 g/ml. The vapour density of air will be

    Consider the following statements and select the correct code. Assertion (A): The velocity of sound in air increased due to the presence of moisture in it. Reason (R): The presence of moisture in air lowers the density of air.
