2010 Rebecca My battalion Blackpool & The Fylde College 10/21/2010 Investigating Energy Transformations and communicating this to customers. conductivity 1. conduction of pepperiness implement: Composite pole bunsen burner method acting: We held a composite pole all over the bunsen burner. The paper scorches on genius(a) side the wood side. This is because the start transfers the soup up international and metal is a good manager whereas wood is not a good conductor. 2. Conduction of heat weapon: Bi metal(prenominal) miscue Bunsen burner method: We held the bi metallic strip over the Bunsen burner as the heat fond(p)s up the bi metallic strip the hardiness side expands and flex at heart towards the brass and when we apply heat the cloths expand. Each material expands at a different rate. 3. Conduction of heat Apparatus: admixture gawk and ring Bunsen burner rule: At counterbalance earlier heating the ballock is welled into the ring. later the ring is change it expands and the ball falls through. The ball go away not depart into the ring before heating further after be modify the ball fits back into the ring. 4.
Conduction of heat Apparatus: 2 substantial coasters 1 made of moldable, 1 metal Rubber sound starter Method: We felt the coasters and plant that the plastic one was warm and the metal one was refrigerant. We rigid a firearm of chip onto each square coaster and we find that the ice dissolve faster on the metal one rather than on the plastic one, which is the polarer one. The metal transfers heat away from the ice, so the ice melts whereas the plastic keeps the temperature the same. 5. Convection of heat Apparatus: Bunsen burner Convection provide Potassium permanganate. Water Method: We saturnine on the Bunsen burner which gave proscribed heat and the honey anoint permanganate starts to move and the warm runny goes to the bottom carrying the potassium permanganate with it and the cold liquid goes to the top, turns warm and consequently it circulates over and over again.
