Abstract: One is to determine the gap energy of cadmium sulfide semiconductor thin film using the equation: Eg = h.c/ is the signal of the long wavelength limit of the absorption peaks (measured in the lab). The reaction between cadmium sulfide and NH3‚ in the presents of thiourea yield a of 579(nm). The % error of the reaction is 1.24%. Introduction: There are 3 types of metals for electricity conducting: metallic conductor‚ semiconductor‚ and superconductor. Metallic conductors

absorbed or emitted heat or for determining specific heats.” While direct calorimeters measure the amount of heat produced in a small chamber‚ indirect calorimeters measure the amount of heat produced by taking into account the amount of consumption of oxygen and elimination of carbon dioxide. Both contain the same concept‚ but have a different approach. Indirect calorimetry is the preferable way for physiologists to measure the amount of oxygen being consumed and carbon dioxide and nitrogen waste being

Dr Montessori emphasises the importance of the development of imagination. How do cultural activities in a Montessori prepared environment aid in this development? Imagination‚ also called the faculty of imagining‚ is the ability of forming mental images‚ sensations and concepts‚ in a moment when they are not perceived through sight‚ hearing or other senses. Imagination is the work of the mind that helps create fantasy. Imagination helps provide meaning to experience and understanding to knowledge;
