2. In the first week of class, we encountered the following formula: where c is the specific heat of the substance. Now that we know a little more, we may see that the formula is ambiguous, since no particular process by which the temperature increases is specified. Let us explore this point a bit more carefully. a) Assum curves ("isotherms"). After determining which isotherm represents the lower temperature, label the colder isotherm temperature Ti and the warmer one T2. Thus,...
3. An ideal gas is initially at a certain pressure and volume. It expands until its volume is four times the initial volume. This is done through an isobaric, an isothermal, and an adiabatic process, respectively. During which of the processes a) ...is the work done by the gas greatest? b)... is the smallest amount of work done by the gas? c) does the internal energy increase? d) ...does the internal energy decrease? e)... does the largest amount of heat...
2. Isochoric/Adiabatic/Isobaric Cycle (10 pts) A heat engine using a monatomic gas follows the cycle shown in the PV diagram to the right. Between stages 1 and 2 the gas is at a constant volume, and between 2 and 3 no heat is transferred in or out, between 3 and 1 the pressure is held constant (a) For each stage of this process, calculate in Joules the heat, Q, transferred to the gas, and the work, W, done by the...

In this question, assume no changes in Ek or Ep (a) In one cycle of a heat engine: 70 J are input by working, 90 J are output by working, 100 J are input by heating, 80 J are output by heating. Write down which one of the following is true: (A) |Wnet-160 J (B) Iw.et-20 J (C) η-0.25 (b) For a fixed amount of gas,...
A polytropic process for an ideal gas in one in which pressure and volume are related by = const., where n is a constant. It is a generalization of the special processes considered earlier. Thus n = 0 defines an isobaric process, n = cp/cv an adiabatic process, n = 1 an isothermal process, and n = 8 an isochoric process. Suppose 1 kg of dry air at 280 K and 100 kPa undergoes a polytropic expansion in which the...
Part A Constants One mole of ideal gas is slowly compressed to one-third of its original volume. In this compression, the work done on the gas has magnitude 694 J. For the gas, Cp 7R/2. If the process is isothermal, what is the heat flow Q for the gas? Express your answer to three significant figures and include the appropriate units.

Question 6 1 pts Which one of the following processes is endothermic? O Steam condenses to liquid water. O Propane gas burns in a gas grill. O Liquid sodium freezing to a solid O Water evaporates from your skin after stepping out of the shower O Water freezes to form ice.
Adiabatic Process An adiabatic process is defined to be one in which there is no heat transfer-that is, Q-0. Processes that are nearly adiabatic can be achieved by using very effective insulation. Don't use scientific notations in your answers. Case 1. A 0.4-mol monatomic ideal gas system undergoes an adiabatic expansion, which results in a temperature decrease of 30K (a) What is the change in internal energy? Include a proper sign. Keep 2 decimal places. (5 attempts remaining) (b) What...
