Free energy changes determine if a reaction is endothermic or exothermic. Processes in nature are driven in two directions: toward least MAIN IDEA enthalpy and toward greatest entropy. When these two oppose each other, the dominant factor determines th direction of change. As a way to predict which factor will dominate fora given system, a function has been defined to relate the enthalpy and entropy factors at a given temperature tropy and constant pressure. This combined enthalpy-entropy function is callepd t free energy, G, of the system; it is also called Gibbs free energy. This function simultaneously assesses the tendencies for enthalpy and entropy to change. Natural processes proceed in the direction that lowersthefree energy of a system. Only the change in free energy can be measured. It can be defined in terms of changes in enthalpy and entropy. At a constant pressure and temperature, the free-energy change, AG, of a system is defined as the difference between the change in enthalpy, AH, and the product of the Kelvin temperature and the entropy change, which is defined as TAS. Free Energy Change AGO= AH°- TASO Note that this expression is for substances in their standard states. The product TAS and the quantities AG and AHhave the same umor usually kJ. The units of AS for use in this equation are usually N If AG<0, the reaction is spontaneous. AH and AS in the free-energy equation can have positive or negative values. This leads to four possible combinations of terms.

人eg 7Zs pgssgge gzの gpsyer 万e 9zes77o725 のe/の必 Im nearly all established democracies, television has become the preeminent mass medium Television is a visual, credible and easily digested format which reaches almost every househod. providing the main source of political information. Im election campaigns。for instance, the teleyision studio has become the main site of batde. The candidates participate through appearing on interviews, debates and talk show: merely appearing on television confers some status and recognition on them. Of course, the political significance of television goes far beyond elections. Huge numbers of ordinary voters watch the evening news and it is here,( A ),that television has most infuence. Through their assumptions about newsworthiness, editors resolve their daily problem of reducing a day's worth of world events to ( 1 ) than 30 minutes on the evening news. Because news programs focus on the exceptional, often negative, their content is always an unrepresentative sample of events. For example, policy failures receive ( 2 ) attenton than policy successes. Similarly, corruption is a story but integrity is not. Necessarily。 television is a distorting mirror on the world. The more Compressed news coverage becomes,the ( 3 ) accurate the 征V lens is bound to be. Despite the primacy of television it would be wrong to discount the political significance of the second mass medium, newWspapers. Today, Television tells us what h in context.
