Methane is easily ignited. 38. 11. Liquid Viscosity ( L) is a measure of the resistance of a fluid to dynamic change. Bitumen is a dense viscous material,dark black or brown in color,used as a binding and waterproofing material. Strong intermolecular forces between molecules hold them together and resist movement of layers past one another. Inter molecular forces exist between molecules and influence the physical properties. c. org Viscosity: The viscosity is a physical property of matter. pro 2016.
