EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered

some sociologists may face when using experiments in their research. (20 marks) (January 2009) MODEL ANSWER Experiments are the preferred scientific method. There are two main types of experiments. The classic scientific experiment takes place in a laboratory in controlled conditions. By contrast field experiments take place in more natural but less controlled experiments. Although experiments are very successful in science they are rarely used in Sociology for the following reasons. Validity
