• evaporation is a physical change
it is in a liquid state
in room temperature
nitric acid - HNO3
Hope it's correct! :)
Answer: option d i think
Dispersion forces
Relative molecular mass
Alkanes experience only dispersion forces. Dispersion forces increase with increasevin the relative molecular mass of the compounds. Hence a higher relative molecular mass implies greater dispersion forces and a greater boiling point.
