What type of energy does the steam in a steam turbine have?
It is heat energy. The turbine turns heat energy into mechanical energy.
How do heat engines use heat to do mechanical work?
Heat engines convert thermal energy into mechanical work by utilizing the principles of thermodynamics. They absorb heat from a high-temperature source, which causes a working fluid (like steam or gas) to expand and perform work, typically by moving a piston. As the fluid expands, it does work on the surroundings, and then it releases some heat to a lower-temperature sink before being compressed to repeat the cycle. This continuous process allows the engine to convert a portion of the absorbed heat energy into useful mechanical work.
What device can convert heat to machinical energy?
A device that converts heat to mechanical energy is called a heat engine. Heat engines operate by using thermal energy from a heat source to perform work, usually through a cyclic process involving the expansion and contraction of gases or fluids. Common examples include steam engines and internal combustion engines, which harness heat from fuel combustion to produce mechanical power.

What was James Joule famous for?
James Joule was famous for his work in the field of thermodynamics, particularly for discovering the relationship between mechanical work and heat energy. This led to the development of the first law of thermodynamics, also known as the conservation of energy principle. Joule's experiments helped establish the concept of the mechanical equivalent of heat.
What is James joule famous for?
James Joule is famous for his work in the field of physics, particularly for establishing the relationship between heat and mechanical work. He formulated the law of conservation of energy and the first law of thermodynamics, which are fundamental principles in our understanding of energy. Joule also developed the concept of the mechanical equivalent of heat, which quantitatively relates mechanical work to heat energy.
