Experiment 2 Equipment needed: 1 empty aluminum soda can 1 ice bath (plastic) filled with ice water 1 hot plate 1 pair crucible tongs 1 Thermometer Place the aluminum can on the hot plate. Pour a few mL of water into the can, and heat until the water boils (evidenced by a large quantity of steam evolving from the can). Lift the can off the plate using the crucible tongs and drop it upside down into the beaker of ice water. Record your observations below. In this experiment, volume is held constant because the walls of the container are rigid. The number of moles is held constant because the hole in the can is sealed when it is turned upside down and immersed in the water/ice bath. Temperature of the water in the ice bath 14∘C=287.15 K Observations: 1. Calculations: a. T1​( in K)=100∘C=373 K b. T2​( in K)=20∘C=293.15 K c. P1​( in atm)=1.0 atm d. P2​ calculated = e. Calculation for P2​ What caused the change in the can's appearance? Explain your observations.
