Aim: To observe what happens when you introduce packing pallets and cold water.
Materials: 1 100 ml beaker, 40 ml of cold tap water, 1 packing pallets
Method: We filled the beaker with 40 ml’s of Cold tap water. We then placed the pallets into water. We observed for 20 minutes. At the start the packing pallets where floating, now they are submerged 1 cm under water, they then broke into 5 separate pieces.
Results: How long did it take for the Pallets to submerge and break up= 20 minutes
How far did the pallets submerge= 1 cm
Discussion: They submerged because the water pressure was pushing them down and pulling them apart. It might have taken less time if we used hot water?
Conclusion: It takes 20 minutes for packing pallets to submerge and dived up in water.
