6 Measurement of Energy In Chemical reaction
International identity of stantar for energy that is joule(J) what alighted from kinetic energy 1 J = 1 kgm²/s² 1 J with number of energies owned by an object with mass 2 kg and speed of 1 m/s² ( if(when in set of English, object with mass 4,4 lb and speed of 147 feet/menit or 2,2 mil/jam Set of smaller energy is used [by] erg 1 erg = 1. 10⁻⁷. J Energy involving in reaction of between reactants of the size molecule usually set of used to be large size that is kilojoule ( 1KJ = 1000J) All form of energa can be changed to form of temperature Hal.: 6 Isi dengan Judul Halaman Terkait

Continuation Way to determine temperature expressed with calorie ( 1 kal) 1 kal expressed as temperature amounts needed to by meneikkan temperature 1g water with temperature of 15°C equal to 1°C 1 kal = 4,184 J ( 1KKal = 4,184 KJ) Hal.: 7 Isi dengan Judul Halaman Terkait

8 Heat Of Reaction And Thermochemistry
System is becoming cynosure Area of is outside system If(when a system experiences change hence peripatetic system from situation of one to other situation Adiabatic change is if(when system isolated from area of so that there is no hot flowable During there are adibatic change will experience exothermic reaction or endothermic reaction Isothermic change is perubhan at permanent temperature The relation of systems and area Hal.: 8 Isi dengan Judul Halaman Terkait
