Robert answered 4 years ago. BMW if taken care of will last a very long time. When I was younger all my BMW's were over 200,000 miles and never had an issue (besides the normal wear and tear stuff). The vehicle you are looking at has the N52 engine in both of them.
Photons in this context do not collide with one another, and so heat transport by electromagnetic radiation is conceptually distinct from heat conduction by microscopic diffusion and collisions of material particles and phonons. But the distinction is often not easily observed, unless the material is semi-transparent.
As they collide, the faster molecules give up some of their energy to the slower molecules. The slower molecules gain more thermal energy and collide with other molecules in the cooler object. This process continues until heat energy from the warmer object spreads throughout the cooler object. Some substances conduct heat more easily than others. Solids are better conductor than liquids and liquids are better conductor than gases.
