     On a day when the barometer reads 755 mm of mercury (mm hg), a tire pressure gage reads 204 kPa. The absolute pressure in the tire is:  1.54 mHg  204 kPa  100 kPa  2.29 mHg  A specific property is also:  an extensive property  the product of two extensive properties  a mass dependent property  an intensive property 
  
  Solution
Converting the gage pressure to mmHg gives
Pg = 204(103) / [13,595 (9.807)] = 1.53 mHg.
P = Patmo + Pg = 1.53 + 0.755 = 2.29 mHg.
therefore, the option d is correct.
A particularly important type of intensive property is the specific property, which is always given on a unit mass basis.
therefore, the option d is correct.
