Basically, we name hydrocarbon in two ways. They are;
Trival system of nomenclature: This system was used on past. They were given name knowing their sources from which hydrocarbon are obtained. On this naming we don't use scientific rules and structural values. For example; methane was named from marsh gas.
IUPAC system of nomenclature: As the above method was not standard. IUPAC (International Union of pure and applied chemistry) improved the system and the started naming hydrocarbon. The IUPAC name of any compound contains two parts: root word and suffix. Example: Methane is named from root word <em>Meth</em> as it <u>has one no.of carbon</u> and suffix <em>ane</em> as it <u>has <em>single</em> <em>bonding</em>.</u>
Pressure of the gas P1 = 30.7 kpa When it doubled P2 = 61.4 kpa Temperature T1 = 0 => T1 =. 0 + 273 =273 Temperature T2 =? We have pressure temperature equation P1T1 = P2T2 => T2 = P1T1 / P2 = (30.7 x 273) / 61.4 = 136.5 So the temperature for doubling the pressure is 136.5.
