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

P_g = 204(10³) / [13,595 (9.807)] = 1.53 mHg.

P = P_atmo + P_g = 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.
