34.05 mL of phosphorus vapour weighs 0.0625 g at 546 ∘C and 0.1 bar pressure. What is the molar mass of phosphorus?
In a gravity free cabin, a non-conducting liquid of surface tension T and possessing uniform volume charge density p is sprayed into large number of drops. After spraying, the drops float around in the cabin and keep on breaking apart into smaller drops and coalescing into larger drops. While floating, the electrostatic forces between the drops are negligible. Estimate radius of the drops when their number reaches a stable value.
A liquid is in equilibrium with its vapour at its boiling point. On average, the molecules in the two phases have equal
