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.

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.
*** 32. A double-chambered container contains one mole of helium in one of its 1000 cm³ Pull to volume chambers. The container is well-insulated, and of low specific heat, so that no appre- remove ciable heat is added to the gas during the process we describe. The gas is initially at a tempera- ture of 300 K and a pressure of 1 atmosphere. The partition between the two chambers is then quickly raised, and the gas expands freely to fill the entire container. Whenever a monatomic gas like helium doubles its volume adiabatically like this, the pressure in the gas will drop to 0.315 of what it was before (for reasons that we did not explain in this chapter), so the final 1000 cm3 1000 cm³ pressure of the expanded gas will be 0.315 atmospheres. a) What is the temperature of the gas after the expansion? b) What is the change in the internal energy of the gas? c) How much heat is added to the gas? [Hint: Maybe read the problem again.] d) How much work is done by the gas as it expands? [Hint:…
