What does james watt mean when he says “after it has done its office?”

Answer 1

When James Watt says "after it has done its office," he is referring to the concept of efficiency in a steam engine. He is talking about the process of converting heat energy into mechanical work. Once the steam engine has completed its task or performed its function, i.e., after it has accomplished the desired work, it does not retain the heat energy for further use. Instead, the energy is released into the environment as waste. Watt's statement emphasizes the importance of optimizing the efficiency of steam engines to minimize energy loss and improve overall performance.
