one way a COOLING SYSTEM thermostat is a temperature-sensitive valve, inside it has a pellet of wax(is more like a chamber full of wax) enclosed in a cylinder piston chamber.when heated the pellet expands and pushes against the return spring to open the valve. when the engine cools the wax pellet will retract and the oposite will occur. it would be easier if i could show you an expanded view of a thermostat

A car thermostat regulates the engine temperature by controlling the flow of coolant. When the engine is cold, the thermostat remains closed, allowing the coolant to circulate within the engine to warm up quickly. As the engine reaches operating temperature, the thermostat gradually opens to allow coolant to flow through the radiator to dissipate heat. This cycle helps maintain optimal engine temperature for efficiency and performance.
Examples of technologies that physics is concerned with include semiconductors in electronics, lasers in various applications such as medicine and communication, and optics for imaging systems like cameras and telescopes. Physics plays a crucial role in understanding the fundamental principles behind these technologies and advancing their development.
The driving force behind the principles of physics is the pursuit of understanding and explaining the fundamental laws that govern the behavior of the universe. Physics seeks to uncover the underlying principles that govern the interactions of matter and energy, and to use this knowledge to predict and explain the behavior of physical systems.
The secret behind the physics hand trick that seems to defy gravity is the manipulation of forces and balance. By positioning your fingers and hand in a specific way, you can create the illusion that an object is floating or defying gravity. This trick relies on the principles of physics, such as center of mass and equilibrium, to create the optical illusion.
Thomson scattering is a process where electromagnetic radiation is scattered by free charged particles. In plasma physics, it is used to measure the properties of plasma, such as temperature and density, by analyzing the scattered light. This technique helps researchers understand the behavior of plasma in various conditions, such as in fusion experiments or astrophysical environments.
Fidget spinners spin due to the conservation of angular momentum. When you flick the spinner, you give it angular momentum, which is then conserved as the spinner spins. The physics behind this involves the distribution of mass in the spinner and the friction in the bearings, which allows the spinner to keep spinning for a longer time.
