Key terms enthalpy the total amount of energy in a system, including both the internal energy and the energy needed to displace its environment fluidity A measure of the extent to which something is fluid. The reciprocal of its viscosity. plasma a state of matter consisting of partially ionized gas shear stress The component of stress that causes parallel layers of a material to move relative to each other in their own planes. sublimation the transition of a substance from the solid phase directly to the vapor state such that it does not pass through the intermediate, liquid phase viscosity A quantity expressing the magnitude of internal friction in a fluid, as measured by the force per unit area resisting uniform flow.
