Abstract: A method for determining a volume change of a viscous liquid during a physical or chemical process is disclosed. The volume change of the viscous liquid is determined by confining a layer of a viscous liquid on a portion of a rigid body and then measuring the linear (one dimensional) displacement of a planar surface formed thereon, as the viscous liquid undergoes the physical or chemical process. The surface of the layer of the viscous liquid is planar relative to the rigid body.
