👉 The Swedish fluid, also known as the Swedish vapor phase or the vapor phase of water, is a state of matter that exists at temperatures above 100°C (212°F) and pressures below 22.1 MPa (about 322 psi). In this state, water exists as a vapor rather than liquid or solid, and it is often referred to as steam. This phase transition occurs when water molecules gain enough kinetic energy to overcome the intermolecular forces holding them in liquid form, allowing them to move freely and occupy the volume of their container. The Swedish fluid is significant in various industrial processes, such as power generation and chemical manufacturing, where efficient heat transfer and phase change are crucial.
