the science lab. In science‚ we would participate in a lab. One of my favorite labs was the owl pellet dissection. Owl pellets are owl throw up. In owl pellets you can find the bones of animals the owl consumed. In this lab we were to take out the bones we found in the pellet and construct the animal we found inside. Most people‚ like me‚ had a sort of rodent‚ but some people found birds in their pellet. Another one of my favorite things we did in science was the Sharpie tie dye lab in fifth grade

Introduction In thermo-fluid sciences‚ the measurement of temperature plays a key role. During this lab we tested two different types of thermocouples‚ a T-type and a J-type. Measuring with a thermocouple allows us to measure the temperature difference between two junctions. There are several laws that deal with the thermocouples and reading of temperatures. We use the first law of thermodynamics which states that there is a conservation of energy. Also the law of homogenous metals is in

Overview A transistor is a semiconductor device that amplifies and switches electrical currents. They are the core component of any modern electronic devices‚ such as computer‚ telephones and other electronics. Nowadays most transistors are use to produce integrated circuits. There were a numerous inventions‚ or problems with the inventions that lead to the birth of the transistor. Radio signals‚ could be sent carrying information over a long distance away; the only problem was there was no device

ay from printed circuit boards (PCBs) that used copper containing thick- lm pastes on rigid substrates‚ which were patterned using a two-step masking and etching process. This process resulted in a surfeit of waste and was expensive due to laborintensive processing of the nal device. By contrast‚ conductive inks are now available that use existing printing technologies such as screen‚ gravure‚ exographic‚ offset‚ and inkjet to print conductive traces directly onto rigid and exible substrates relatively

Heat Conduction along a Composite Bar Objective To study the conduction of heat along a composite bar and evaluate the overall heat transfer coefficient. Theory Thermal conduction is the mode of heat transfer which occurs in a material by virtue of a temperature gradient within it. A solid is chosen for the demonstration of pure conduction since both liquids and gasses exhibit excessive convective heat transfer. In a practical situation‚ heat conduction occurs in three detentions‚ a complexity

large distance between atoms in a gas: fewer collisions between atoms means less conduction. Conductivity of gases increases with temperature. Conductivity increases with increasing pressure from vacuum up to a critical point that the density of the gas is such that molecules of the gas may be expected to collide with each other before they transfer heat from one surface to another. After this point conductivity increases only slightly with increasing pressure and density. Thermal contact conductance is

An electric conductivity monitor (Model DDS 307) was used to measure the conductivity for distilled water and solutions. The penetration of the NaCl through the membrane was detected via the change in conductivity of the permeate water according to equation (3.1). R(%) = (C_1-C_2)/C_1 × 100 ………………. (3.1) where R:

voltage is applied to the electrodes at both ends of the product such as both ends of vessel. The rate of heating is directly proportional to the square of the electric field strength and electrical conductivity. The most important factor that effectuates the rate of heating is electrical conductivity and its temperature dependence.
