I know the boiling point of dilute solutions is high, even above that of  
water.
But i have heated CuCl to about 50C once, and smelled a huge quantity of  
fumes from that tiny glass, much more than from the 2 liter tank (no smell  
noticeable). So i know the heating caused much more fumes to be released  
than normal. 38% HCl boils at 48C, i think even when not boiling higher  
temperature means much more fumes, like a steaming cup of tea.
