At room themperature, the average speed of Helium is Helium is higher than of Oxygen by a factor of :

Calculate the rms speed of helium atoms at 127^(@) C .

The ratio of densities of helium and hydrogen is 4 : 2. Calculate the temperature at which the speed of sound in helium will be equal to speed in hydrogen at 27^(@) C ?

Assetion : Equal masses of helium and oxygen gases are given equal quantities of heat. The rise in temperature of helium is greater thant that in case of oxygen. Reason : The molecular mass of oxygen is more than molecular mass of helium.

At what temperature the rms speed of oxygen atom equal to rms speed of helium gas atom at -10^(@)C ? Atomic mass of helium = 4 Atomic mass of oxygen = 32

Helium mixed with oxygen is used in the treatment of

Helium mixed with oxygen is used in the treatment of

At a same temperature , hydrgone is more soluble in water than helium . Which of them will have a higher value of K_(H) and why ?
