To clarify the results of the preceding problem, we look at a simpler example. Benchmark Processor
X Y Z
1 20 10 40
2 40 80 20
1. Compute the arithmetic mean value for each system using X as the reference machine and then using Y as the reference machine. Argue that intuitively, the three machines have roughly equivalent performance and that the arithmetic mean gives misleading results.
2. Compute the geometric mean value for each system, using X as the reference machine and then using Y as the reference machine. Argue that the results are more realistic than with the arithmetic mean.

The answer is access.

answer: when the substance contain the two parts (polar and non-polar) like soap.

explanation:

soap is produced from the basic hydrolysis of ester "saponification", it is considered as a salt of hydrocarbons. the soap molecule contains the two parts: a polar group   (-coo-na+) and a non-polar group (r-hydrocarbon part). the polar group is called the head and the tail is the non-polar group. the polar group is hydrophilic in nature (water loving) and the non-polar group is hydrophobic in nature (water repelling).the polar/non-polar nature of a substance is useful that it can dissolve the non-polar substances by the polar part and also can dissolve the polar substances by the non-polar part. it commonly used in detergents and soaps.
