Study Notes
Brake System
- Brake pads are a crucial component of a brake system, responsible for converting kinetic energy into heat energy to slow down or stop a vehicle.
- Key components of a brake system include brake pads, brake rotors, brake calipers, and brake fluid.
Brake Fluid
- Low brake fluid levels in a brake system can cause air to enter the system, leading to a spongy brake pedal, reduced braking power, and potential brake failure.
Laws of Thermodynamics
- The first law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another.
- The second law of thermodynamics describes the direction of spontaneous processes, stating that the total entropy of an isolated system always increases over time.
Adiabatic Process
- An adiabatic process is an example of a thermodynamic process in which there is no heat transfer between the system and its surroundings, resulting in a change in temperature.
- Examples of adiabatic processes include the expansion of a gas in a piston, the compression of a gas in a cylinder, and the rapid expansion of gases in a combustion engine.
