Fluids with high expansion ratios that do not leave the liquid state

  1. Sep 15, 2014 #1
    Hey guys, I've been doing a lot of research looking for a fluid that has a high expansion ratio that does not leave the liquid state.

    the idea is that the fluid could either:

    - using heat will expand and contract using hot and cold cycles
    - using electricity (not necessarily needing heat) to expand then contract by itself or by de-energizing the fluid
    - a fluid while contracting will create a great amount of vacuum. (preferably able to do at low temps, around room temperature)

    Please excuse my lack of terminology, I'm working off of my basic knowledge from highschool chem and physics

    Thank you for your help in advance guys.
