IAPWS

IAPWS is a group of really smart people who study how water and steam behave when they get really hot or really cold. They use math and science to help us understand how to build things like power plants and engines that use water and steam to make energy. They also create rules and formulas that help scientists and engineers make better predictions about how water and steam will act in different situations. Think of it like a group of grown-up puzzle makers who help us understand how water and steam move and how we can use that to make things work better!
