1. ____________ is the property which enables oil to spread over and adhere to the surface of the bearing.

2. ____________ is the lowest temperature at which the oil burns continuously.

5. During compression process the temperature ____________ and attains its maximum value at the end of combustion process.

6. Which of the following are the properties of lubricants?

7. The pumping loss is negligible in two-stroke cycle engines.

8. The objective of lubrication is to reduce friction between the parts having relative motion.

9. ____________ is the transfer of heat within a fluid by mixing of one portion of fluid with another.
