At what temperature density of air is maximum?

At room temperature, the density of water is 1.0 g/mL and the density of ethanol is 0.789 g/mL. What volume of ethanol contains the same number of molecules as are present in 175 mL of water?

draw a graph showing the variation of volume of a given mass of water with temperature from 0°C . In the graph mark the temperature at which water has maximum density.

Discovery, of Haber’s process for manufacture of ammonia is considered to be one of the principal discoveries of twentieth century. What is the temperature condition for maximum yield of ammonia? Justify.

If air contains 'N_2' and 'O_2 in^prime' vòlume ratio '4: 1', the average vapour density of air is

Using the equation of state pV=nRT show that at a given temperature , the density of the gas is proportional to the gas pressure p.

Water has maximum density at
