Heat engines are really interesting! They take heat energy and turn it into mechanical work.
This process is connected to some important rules called the laws of thermodynamics. Here are two of them:
First Law: This law tells us that energy is conserved. This means that the energy we put in is equal to the energy we get out.
Second Law: This law explains that not all heat can be turned into work. This is where the idea of efficiency comes in.
Efficiency matters a lot! It tells us how well an engine is using the energy it gets.
For instance, if an engine has an efficiency of 30%, that means it turns 30% of the heat energy into useful work. This is a big deal because it helps us understand how well the engine is doing its job! 🛠️
