Convection

Introduction         Heat is transferred with convection, conduction and radiation. Convection is the transfer of heat up by means of the causal agent of matter. Conduction is the transfer of heat or specialism between two objects that argon in contact with whole(prenominal) other. radiation sickness is the transfer of energy through electromagnetic waves. In this lab we conducted four separate experiments. The experiments test to see how convection currents take a leak effects on an ecosystem. experiment 1         In this experiment, we tested to see if liquids in an ecosystem could ca manipulation convection currents. We poured spicy piddle into a flask. We diagonal it with half a teaspoonful of potassium permanganate (just to eliminate it from others). The flask was plugged with a double- hollerd good-for-nothing stopper. The olympian colored water in the flask drop down to the bottom of the graduate cylinder. synopsis 1         The purple bleached water came come out of the closet of genius of the internal-combustion engine droppers into the large portion of voluptuous water, which wasn?t as hot as the water in the flask. The purple water reached the mount while the clear water was be pushed down. This illustrated convection of liquids. The currents eventually reached thermic equilibrium and convection stopped. All the water was purple and reached iodin temperature. Experiment 2         There was a artificial juice band container that was cut in the middle to puddle a window. both holes were made on the top and viscous out of the holes were unreal toilet paper lineaments. Inside the box was a slim crucible containing hydraulic acid, ammonium hydroxide and directly to a lower place the toilet paper roll was a lit candle. The window was covered with plastic wrap so that nothing could escape. Analysis         The candle was a heat informa nt that sped up the movement of the molecule! s. The molecules were less dense and you could see bullet train advance from the right toilet paper roll. Ammonium Chloride and water created salt. The heat leaving the container created a convection current, and the salt released a purity splosh in the air. Experiment 3 We had split up into groups of four. to each one group got lead separate pieces of form that we had to gather into horizontal rectangles as thin as possible. They were all zoftig on top of each other when shaped. The objective was to use 3 different techniques that put pressure on the layered pieces of clay. These forces had to any push or pull like weighing auto tectonics. The clay was pulled apart, pushed inward way out up and pushed inward going down. Analysis         When the clay was pulled apart, it split in two. When the clay was pushed in it either created a mountain (volcano) or a hole in the ground. On earth, plate techtonics create forces which are ca utilize by convectio n currents. Under the ground magma is causing convection currents from heat and pressure. The experiment shows what great power happen in real life if plates begin to slide. close         Convection currents affect all living organisms. Pressure, heat and time plays a big role in transfer of heat and the carry of different materials. In all these experiments we saw convection in three different ways. The scratch was in the flask, when it showed convection of a liquid. The second one we saw was the convection of a gas in the juice box. The terzetto and final one we saw was the convection of a solid when we used the clay to show plate tectonics. If you want to get a full essay, frame it on our website: OrderCustomPaper.com
