Solid state physics II Testing a Peltier Element Abstract The purpose of the experiment was to investigate the cooling properties of a Peltier element and specifically the relation between the electric current through the element and the temperature in a refrigerator cooled by the element. The “refrigerator” consisted of a cavity in a block of polystyrene foam with the Peltier element covering the opening of the cavity. A fan on top

x Biology 11 Ms. Zwart 06.09.13 The Cooling Curve of Water Variables: Independent Variable: The independent variable is heat; we measure the temperature with a thermometer‚ which has a systematic error of ± 0.5 °C. Dependent Variable: The dependent variable is time; we know when 30seconds pass with the use of a stopwatch‚ which has a systematic error of ± 1 second. Controlled Variables: The controlled variables used in this experiment are; a 400ml beaker with the systematic error

decision to make. He must decide if he should invest in property and build the “Citic Tower II”. Under the current conditions‚ the current net present value is negative‚ which is one of the factors that Larry is using to decide. Another concern is that the commercial real estate market is very cyclical in the area. Also‚ with the current economic conditions‚ there is not really a guarantee that the “Citic Tower II” will survive in the area‚ which another concern for Larry Yung. In terms of the positives

CRITIQUE: SEARS TOWER I remember being passionate about the design of a certain building standing in the heart of the United States of America when I was 14-15 years old. Well‚ I still am.

The Ivory Tower It rose up inside of me; the sense of fear was undeniable‚ as if it were a penned bull being taunted and ready to charge. The Clean‚ sickly‚ astringent smell that clung to the air made me feel nauseated. Sweat dripped in beads down my forehead‚ as my eyes darted around the room trying to catch any sign of movement.

THERMOELECTRIC POWERED CAR 1. AIM OF THE PROJECT This concept behind the project is thermoelectric generation that has been known from sometime‚ but the practical implementation of this concept is quite difficult. The idea behind this project is to make a Car that is powered by thermoelectric source‚ i.e. to build a car that moves with temperature difference. This concept has not been explored earlier but a lot of research can be done in this regard. We will be presenting a practically running
