Unformatted text preview: 2. Work (w) is energy transferred by a force a. w = Force x Distance B. E system = q system + w system 1. q system is heat transferred to the system 2. w system is work done on the system G. Types of energy 1. Kinetic: K.E.= 1/2 mv 2 2. Potential: P.E. = mgh C. First Law of Thermodynamics (Law of Conservation of Energy) 1. The total energy of the universe is constant 2. Energy can neither be created nor destroyed 3. E universe = in any process III. Three Types of Systems A. Open System: Transfers both heat and matter to surroundings B. Closed System: Transfers only heat to its surroundings C. Isolated System: No exchange with its surroundings IV. Calculations A. q sys = -q surr B. q sample = S sample x m sample x T 1. S sample is the specific heat capacity of the sample 2. m sample is the mass of the sample 3. T is the temperature change...
