Method
1. Scissors were used to cut the rubber band, making the rubber band one straight line instead of a circular shape.
2. One end of the rubber band was securely tied to the middle of the skewer. The other end was securely tied to the hook of the 100g slotted steel weight.
3. The skewer was placed along the rim of the 250mL measuring cylinder, which allowed the rubber band and steel weight to hang within the measuring cylinder. Play dough was placed, to secure the skewer, to the edges of the measuring cylinder (the setup of the structure described in Step 2 & 3 is shown in Figure 2).
4. Water was boiled in a kettle, and after the water had been boiled it was poured into a pan, over a stove top. The water was continuously checked upon until it had reached as close to boiling …show more content…
The thermometer was immediately placed inside the water, and the temperature was measured and recorded as close to boiling point as possible. A ruler was then placed along the side of the measuring cylinder and the stretch length of the rubber band, between the skewer and the steel weight, was recorded.
6. The thermometer was left inside the measuring cylinder. When the water had dropped to 80 0C, the new stretch length of the rubber band, between the skewer and the steel weight, was recorded.
7. Step 6 was repeated at 60 0C, 40 0C and 20 0C (room temperature).
8. The water was poured out of the measuring cylinder, leaving the skewer with the rubber band and steel weight behind.
9. 250mL of cold tap water was poured into a mug, and the temperature of the water was measured. As it was not at melting point yet, the mug was placed inside the freezer. It was continuously checked upon, until the temperature had reached as close to melting point as possible while remaining as liquid water. It was then taken out of the freezer and then immediately poured into the measuring cylinder until it reached the top of the measuring cylinder, ensuing the entire rubber band was submerged under the
