hi, newbie here wants to ask a question:

i wanted to know what would happen if i have an enclosed plastic canister (bottle/tube) 40 % full of pure Methylene Chloride. what would be the effect if i dip this tube in halfway in warm water with temerature56 C( 39.8C   Methylene Chloride's boiling point):

which of the following will occur:
1. the liquid will boil and vaporise to the upper part of the tube where it is cooler and condense?
2. the boiling liquid will build up alot of pressure and blow open my bottle?
3. something else?

this is for a project which i intend to make but i wanted to ask those chemists out there who are familiar before i do something stupid?

thank you in advance
