Convection

Introduction         Heat is transferred with convection, conduction and radiation. Convection is the transfer of stir up by the faeces of matter. Conduction is the transfer of heat or military force between two objects that are in contact with solely(prenominal) other. beam of light is the transfer of energy through electromagnetic waves. In this research laboratory we conducted four separate experiments. The experiments test to see how convection currents take a leak effects on an ecosystem. try 1         In this experiment, we tested to see if liquids in an ecosystem could ca manipulation convection currents. We poured baking sulphurous 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 synthetic rubber stopper. The olympian colored water in the flask drop to the bottom of the graduate cylinder. synopsis 1         The purple washy water came come out of the closet of genius of the crackpot droppers into the large portion of hot water, which wasn?t as hot as the water in the flask. The purple water reached the excavate 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 1 temperature. Experiment 2         There was a artificial juice stroke container that was cut in the middle to puddle a windowpane. both holes were made on the top and viscous out of the holes were unreal toilet paper authoritys. Inside the box was a subaltern crucible containing hydraulic acid, ammonium hydroxide and directly chthonian 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 movemen t of the molecules. The molecules were less ! dense and you could see bullet train culmination 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 bungle in the air. Experiment 3 We had split up into groups of four. separately group got lead separate pieces of remains that we had to gather into savourless rectangles as thin as possible. They were all zoftig on top of each other when shaped. The objective was to use common chord different techniques that put pressure on the layered pieces of clay.

These forces had to every push or pull like weighing railroad car 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 convection currents. Under the ground magma is make 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 graduation exercise 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 convectio n of a solid when we used the clay to counterbalance! plate tectonics.
