I’d say both techies are correct.
Volatility, as applied in gasoline, is quantified by the tendency of the liquid to change to vapor at any given temperature (vaporize). This rate of change might be hard or easy, this depends on the temperature or the pressure. Technician B is also correct. RVP is defined and determined experimentally according to the ratio of the vapor volume to the liquid volume at 100 °F.
