The average heat loss per minute for no cover was -2.36667 °C. Compared to the average heat loss per minute for Styrofoam that was -1.79°C. The cover kept in more heat because it slowed convection in the beaker resulting in a warmer temperature.]]> 2017-04-06 13:05:48 UTC https://padlet.com/lplante1/glmzau4zoifp/wish/165124407 https://padlet.com/lplante1/glmzau4zoifp/wish/165124527 The reference data, the one with no cover, losses the most heat, as expected. The cover that lost the least amount of heat was the aluminum foil at -1.36 per min. This would be the most effective to heat loss and would be the best to use as a cover. The material that lost the most heat was the duck tape at -2.02 per min. ]]> 2017-04-06 13:06:10 UTC https://padlet.com/lplante1/glmzau4zoifp/wish/165124527 https://padlet.com/lplante1/glmzau4zoifp/wish/165124529 We know that the cover material made a difference because the average temperature change was -2.36 degrees per minute, which is changing at a very quick rate. The average temperature change for aluminum foil was -1.36 degrees per minute which is changing at a slightly smaller rate than the beaker with no cover. The aluminum foil cover insulated it better than the beaker with no cover so the cover does make a difference.]]> 2017-04-06 13:06:10 UTC https://padlet.com/lplante1/glmzau4zoifp/wish/165124529 https://padlet.com/lplante1/glmzau4zoifp/wish/165124804 The beaker with out the cover had the greatest average which meant it went down the most through out the experiment. The other beakers with the cover didn't go down as much.]]> 2017-04-06 13:07:00 UTC https://padlet.com/lplante1/glmzau4zoifp/wish/165124804 https://padlet.com/lplante1/glmzau4zoifp/wish/165125568  the cover materiel  makes a difference because the Beaker with No cover lost 2.37 degrees a minute and the Aluminium cover only lost 1.36 degrees a minute ]]> 2017-04-06 13:09:18 UTC https://padlet.com/lplante1/glmzau4zoifp/wish/165125568
