Fluids and Their Properties

The video introduces the WHMIS system, explaining its eight safety symbols used worldwide to identify hazardous materials. It then defines fluids as substances that can flow and have no fixed shape, including gases and liquids. The video explores three main uses of fluids: transporting materials through slurries, shaping materials via superheating, and holding materials, exemplified by toothpaste. Each section provides examples and explanations to enhance understanding.
