Pre-lab 8: Cold Engine The experimental setup for this week's lab consists of a syringe connected to a metal can (reservoir), a cold bath (water - ice mixture) and a "hot" bath (water at room temperature). A schematics of the syringe - reservoir system is shown below. Plunger of mass m Filled with gas (air) Syringe of volume Vcor VH - Volume Vo includes tube + Metal can -Metal can submerged in water of temperature Тс or TH.
