Is a motorcycle in garage an example of isolated system?

No, a motorcycle in a garage is not an example of an isolated system because it is not completely isolated from its surroundings. The garage is not a perfect insulator and there will be some heat exchange between the motorcycle and the outside environment. Additionally, there may be some air movement in and out of the garage, which could also affect the temperature of the motorcycle. Therefore, the motorcycle in the garage is not completely isolated from its surroundings and cannot be considered an isolated system.
