Assertion :Droplets of liquid are usually more spherical in shape than large drops of the same liquid. Reason :Force of surface tension predominates the force of gravity in case of small drops.
A rigid vessel of volume 0.50m3 containing H2 at 20.5∘C and a pressure of 611×103 Pa is connected to a second rigid vessel of volume 0.75m3 containing Ar at 31.2∘C at a pressure of 433×103 Pa. A value separating the two vessels is opened and both are cooled to a temperature of 14.5∘C. What is the final pressure in the vessels?
