A heat engine is a type of system that converts heat or thermal energy into mechanical energy, which can then be used to perform useful work, such as a movement. The below steps record how a heat engine generally work: 1. Heat Input: It all starts when a heat source of high temperature, such as burning fuel, geothermal energy, or solar power, begins to transfer heat energy to the engine. 2. Expansion: The incoming heat causes a working fluid or gas inside the engine to expand. This can cause a piston to move or a turbine to rotate. 3. Work Output: The movement of the piston or rotation of the turbine is turned into useful work. For example, it might power a car's wheels, a generator producing electricity, or any other form of mechanical energy. 4. Heat Exhaust: After delivering work, the fluid or gas will have cooled down, but since it is still hotter than the ambient temperature, it can still be disposed of to a low-temperature heat sink such as the atmosphere or a body of water. This process is often done at a lower pressure to make the exhaust process more efficient. 5. Compression: Lastly, the working fluid or gas is re-compressed to start another cycle. It is then drawn back into the heat source to absorb heat once more, and the cycle begins again. In all these processes, a heat engine operates under the principles of the laws of thermodynamics, particularly the first (energy cannot be created or destroyed, only changed from one form to another) and the second (in any cyclic process the entropy will either increase or remain the same). However, it's important to note that no heat engine can be 100% efficient, due to the 2nd law of thermodynamics. Some of the heat always ends up wasted, often lost in the exhaust process.

Determining the best tire brand depends on various factors such as vehicle type, driving conditions, and personal preferences. However, some leading brands consistently rank high for quality and performance. Michelin is renowned for its long-lasting tires, offering excellent grip and fuel efficiency across various conditions. Continental is another top choice, known for its innovative technology and strong performance in both dry and wet conditions. Bridgestone, with its wide range of products, caters to almost any vehicle and is notable for its durability and reliability. Goodyear tires are praised for their strong performance across many vehicle types and conditions, with a focus on innovation and safety. Ultimately, the best tire brand for you will depend on specific needs, such as winter driving capabilities, off-road performance, or fuel economy.
