This effect was observed as a rise in the object on the platform so is the piston height from state B to C. However, if the air chamber can is placed in the cold bath, the temperature and volume will decrease.

It has two air tubes leading from the cylinder: one going to a pressure sensor (which is measured using the Lab Pro) and the other leading to an air reservoir (aluminum can) that we will immerse in water to change the temperature of the air in the system. Based on your P-V diagram, are you going to use the values for the preparation stage of the experiment or the last values of P, V, and T when the piston returned to the ice-water bath at the end of the cycle as your values for point "A"? 0000039219 00000 n
