- See graph. There is 2 mol of an ideal monatomic gas. The following two point, 4, 2 are given below, 4: P4 = 2atm, T4 = 360K. 2: V2 = 3V4 and P2 = 2P3. 1- 2 Isothermal process. 2 3 → 4 Isothermal process. 3 V The cycle proceeds from 4 →1→ 2 – 3 → 4. Determine the total amount of work done by the gas and the heat supplied to the gas along each portion of the cycle.arrow_forwardExplain how at high pressures the conversion of graphite to diamond can increase the total entropy of the carbon plus its environment.arrow_forwardA student rolls 2 dice (an object that is a cube with faces numbered 1-6). The dice are "fair," meaning that there is an equal chance that each lands on any of its 6 faces. Determine the entropy of the macrostate in which the sum of all the top dice faces equals 4. (For reference, in the cartoon the "top dice face" displays the number "2").arrow_forward
- A gasoline engine uses 2 moles of monoatomic ideal gas as the working substance. Figure 3 shows the thermodynamic cycle taken by the engine. Process a → b is adiabatic, b →c is isochoric, e → d is isobaric and d → a is isochoric. Given Pa = 1.5 x 106 Pa, Va = %3D 6.17 x 10-3 m³, V½ = 2.5 Va and Te = 208 K. Pressure P. P. Pe V.

Isothermal compression from 2 atm and 10 L to 20 atm and 1 L b. Isobaric expansion to return the gas to the original volume of 10 L c. Cooling at constant volume to bring the gas to the original pressure and temperature. Illustrate the steps on a P-V curve. Calculate q, w, ΔU, ΔH, and ΔS for each step and for the cycle.arrow_forwardCalculate the entropy of fusion of a compound at 25 °c given that its enthalpy of fusion is 36 kJ mol-1 at its melting point of 151 °c and the molar heat capacities (at constant pressure) of the liquid and solid forms are 33 J K-1 mol-1 and 17 J K-1 mol- 1, respectively.arrow_forward
- Consider three systems consisting of the same polyatomic gas at different temperatures. Each temperature results in the excitation of different degrees of freedom within the gas. Arrange the given systems, represented by their active degrees of freedom, in order from highest entropy to lowest entropy. all entropies equal purely translational translational, rotational, and vibrational Highest entropy Lowest entropy Answer Bank translational and rotational other entropies equalarrow_forwardAll of the following statements are correct EXCEPT Select the correct response: in any chemical reaction the change in energies of the system and the surroundings are equal in magnitude but opposite in an expanding gas does work on the surroundings, thus w has a negative value. if a reaction occurs at constant pressure, w = E E=q+w (where q equals heat and w equals work). if a reaction occurs at constant volume, q = E. < Previous There will be work done if the direction of the force is perpendicular to the direction of displacement Select the correct response. none of the choices False Both True If during a given physical process the only force acting on an object is friction, which of the following must be assumed in regard t kinetic energy? Select the correct response: X It decreases. It increases It remains constant It cannot be determined from the information givenarrow_forwardThe engine that powers a crane burns fuel at a temperature of 1500 oC. It is cooled by air at a temperature of 20 oC. The crane is used to lift a 1000 kg steel girder 30 m into the air. If the engine is 40 % as efficient as a Carnot engine, what is its thermal efficiency in %?arrow_forward
- What increase in entropy is produced by mixking 20.0kg of 90.0C water with 20.0kg of 10.0C water? Q=3.35x10^6Jarrow_forwardA gas follows pV = bp + cT on an isothermal curve, where p is the pressure, V is the volume, b is a constant, and c is a function of temperature. Show that a temperature scale under an isochoric process can be established with this gas and is identical to that of an ideal gas.arrow_forwardIn 1883, the volcano on Krakatau Island in the Pacific erupted violently in the largest explosion in Earth’s recorded history, destroying much of the island in the process. Global temperature measurements indicate that this explosion reduced the average temperature of Earth by about 1 degree Celsius during the next two decades. Why? Note: The answer to this question might somehow be connected to the first law of thermodynamics. As much as possible, connect the answer to it.arrow_forward
