Dear Bruce "sticking my neck out" Girrell,
An interesting proposition but have you considered that even though the =
gases may have an enormous amount of latent heat, energy will only =
create a rise in temperature if the point of application is at a lower =
temperature. Heat cannot be moved to a location of higher temperature =
without expending effort (doing Work). Think about a Fridge to =
understand
Given a base line temperature you can calculate what the potential heat =
capacity of water is from its specific heat, its latent heat of =
evaporation and the specific heat of the gas combined with the rise in =
temperature. If you take the heat of vaporisation at 100=BA C which =
seems to be 2256.67 Joules per gram (X 18 of a Gram molecular mass), for =
the quantity you intend using and work on a specific heat for liquid =
water of 75.3 Joules per degree K per mol ( gram molecular mass) and the =
Specific heat for gaseous water 33.6 Joules per degree K per Mol then =
you should be able to get a ball park figure for the amount of energy =
needed if there is No Water Gas Reaction. Now work out the =
thermodynamics for Water Gas Reaction to find out the Kinetic Energy =
released by reacting Water with Carbon. If the first is greater than the =
second your hypothesis is supported. If not, it will have been an =
interesting mental exercise.
Best regards,
Ivor
