In the first, we put the right side of the machine in hot water, and the left side of the machine in cool water; However the machine does not have any change because it is has a slowly reaction. Since, the hot water is changed to fire. When the one side of the machine is fired, other side of the machine still in the cool water, the machine starts to spin, and it becomes quicker and quicker. And we change it to one side in hot water, one side in ice, it still spins but slowly. Then we plug in to electricity in the two sides, it spins quick as the first time. It tells us, the different temperature will change electrons' moving, and causes machine spin.
In this lab, we use different mass to put in the top of the small pan and we connect it to a machine to measure pressure. we performed a cycle by following the procedures and create graph of the P vs V diagram.
The graph V vs. P
Each two connect point must have a relationship or in special state. Calculating the Q,W,U by given information. ()
