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 VA Volume Vo includes tube + metal can -Metal can submerged in water of temperature Tc TH. Tube Stopper Figure 1: Schematic of the syringe - reservoir system. The syringe is essentially a glass cylinder fitted with a movable piston (plunger). The markings on the syringe indicate the volume of gas in the syringe, but do not include the additional, unknown volume, Vo, in the gas can and tubing.

Tube Stopper Figure 1: Schematic of the syringe - reservoir system. The syringe is essentially a glass cylinder fitted with a movable piston (plunger). The markings on the syringe indicate the volume of gas in the syringe, but do not include the additional, unknown volume, Vo, in the gas can and tubing.

Problem 2 (Part 2.6 in the lab handout) Consider the syringe mounted horizontally and V₁, the volume indicated on the syringe scale. The syringe is then placed vertically and a new volume value, V, is observed. In both cases, the gas can is placed in the "hot" bath, so the gas temperature is maintained constant. Using free-body diagrams and the ideal gas law for each case, show that the weight, Mg, of the plunger can be expressed as: Mg APatm Vh - Vv V₂ + Vo GAS VS Figure 2: Horizontally mounted (left) vs. vertically mounted (right) syringe. = GAS CO
