Vapor pressure called partial pressure. For example, air at sea level, and saturated with water vapor at 20 °C, has partial pressures of about 2.3 kPa of water, 78 kPa of nitrogen, 21 kPa of oxygen and 0.9 kPa of argon, totaling 102.2 kPa, making the basis for standard atmospheric pressure. Vapor pressure is measured in the standard units of pressure. The International System of Units (SI) recognizes pressure as a derived unit with the dimension of force per area and designates the pascal (Pa) as its standard unit. One pascal is one newton per square meter (N·m or kg·m·s). Experimental measurement
Comparison of Object Pascal and C the ASCII character set codice_47 and codice_48 is a TAB character. In addition to codice_49 type, Object Pascal also has codice_50 to represent Unicode characters. In C, this is usually implemented as a macro or codice_16 with name codice_52, which is simply an alias for codice_24. In Pascal, boolean is an enumerated type. The possible values of boolean are false and true, with ordinal value of false=0 and true=1, other values are undefined. For conversion to integer, ord is used: There is no standard function for integer to boolean, however, the conversion is simple in practice: C has binary valued
