8) The lubricating oil in piston-type compressors is always found in minute amounts in the cylinder bore; compressor operations must always b aintained well below the Auto ignition temperature (AIT) of the oil to prevent explosion. A particular lubricating oil has an AIT of 365°C. Compute ompression ratio required to raise the temperature of air to the AIT of this oil.

Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.
