Why can some asthma medicine (inhalors) not be stored at temperatures higher than 298.15 K? My thinking is either/both the fact that the gas (medicine) obeys the approximations of the Clausius-Clapeyron equation (so it is approximately an ideal gas) and that the pressure of the inhalor gas must be higher than the air pressure. As an ideal gas can be based on 298.15 K, temperatures above 298.15 K would make the air pressure higher than the gas pressure. Do you think my suggestions are correct?
