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...
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...
Problem 2: In a given lab session a group of students performed a sequence of thermodynamic processes to a given gas. Before performing the process the studenta recorded the initial pressure of the gas as being 101.5 kPa and its temperature equal to 2000 The sequence can be described as firstly isochoric heating in which the gas temperature is increased by 25% of its initial temperature, followed by an isothermal compression in which the volume of the gas is reduced...
Please help me about Physics, Thanks. A sample of 1.00 mole of a diatomic ideal gas is intially at temperature 265K........... Thermodynamic Processes involving Ideal Gases-in-class worksheet-(5 points) PHYS 181 Question B (B.) A sample of 1.00 mole of a diatomic ideal gas is initially at temperature 265 K and volume 0.200 m. The gas first undergoes an isobaric expansion, such that its temperature increases by 120.0 K. It then undergoes an adiabatic expansion so that its final volume is...
A, B , D ,E PLEASE SOLVE THEM ( DETAILED SOLUTION + CLEAR HANDWRITING) 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,...
400 moles of an ideal monatomic gas are kept in a cylinder fitted with a light frictionless piston. The gas is maintained at the atmospheric pressure. Heat is added to the gas. The gas consequently expands slowly from an initial volume of 10 m3 to 15 m3. (a) Draw a P-V diagram for this process. (b) Is this thermodynamic process an isothermal expansion, an isobaric expansion or an adiabatic expansion? (c) Calculate the work done by the gas. (d) Calculate...
