The fact that ionic liquids are fundamentally different than molecular liquids means that their physical properties are also qualitatively and quantitatively different. The flexibility that chemists have to select cations and anions implies that media with interesting sets of physical properties may be prepared. Properties such as electric conductivity, vapor pressure, surface tension, melting temperature, heat capacity, thermal conductivity, and thermal stability form the basis of several interesting technology applications. The applications include thermal energy storage and transfer (vapor pressure, heat capacity, thermal conductivity, thermal stability), a thermal battery (electric conductivity, melting temperature), a monopropellant (vapor pressure, heat of formation), a magnetohydrodynamic pump (electric conductivity, viscosity), and an electrowetting lens (vapor pressure, electric conductivity, viscosity). How ionic liquid physical properties relate to these applications will be presented.
