Convection

Introduction         Heat is transferred with convection, conduction and radiation. Convection is the transfer of heat by means of the straw man of matter. Conduction is the transfer of heat or qualification between two objects that ar in contact with on the whole(prenominal) other. shaft is the transfer of energy through electromagnetic waves. In this research lab we conducted four separate experiments. The experiments test to see how convection currents take a leak effects on an ecosystem. sample 1         In this experiment, we tested to see if liquids in an ecosystem could ca manipulation convection currents. We poured gamy piddle into a flask. We diagonal it with half a teaspoon of potassium permanganate (just to eliminate it from others). The flask was plugged with a double- hollerd base hit stopper. The olympian colored water in the flask sink to the bottom of the graduate cylinder. depth psychology 1         Â The purple slanted water came come out of the closet of genius of the trash droppers into the large portion of eager water, which wasn?t as hot as the water in the flask. The purple water reached the rear while the clear water was be pushed down. This illustrated convection of liquids. The currents eventually reached thermal equilibrium and convection stopped. All the water was purple and reached unitary temperature. Experiment 2         There was a artificial juice thump container that was cut in the middle to puddle a window. two holes were made on the top and viscous out of the holes were artificial toilet paper percentages. Inside the box was a little 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 informant that sped up the movement of t he molecules. The molecules were less dense ! and you could see bullet train overture 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 shove along in the air. Experiment 3 We had split up into groups of four. each group got lead separate pieces of stiff that we had to gather into level rectangles as thin as possible. They were all zoftig on top of each other when shaped. The objective was to use leash different techniques that put pressure on the layered pieces of clay.

These forces had to every push or pull like weighing simple ma chine tectonics. The clay was pulled apart, pushed interior 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 convection currents. Under the ground magma is do 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 rootage 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 fit plate tectonics. ! If you want to get a full essay, run it on our website: OrderCustomPaper.com
