(III) In an engine that approximates the Otto cycle (Fig. 20–8), gasoline vapor must be ignited at the end of the cylinder’s adiabatic compression by the spark from a spark plug. The ignition temperature of 87-octane gasoline vapor is about 430°C and, assuming that the working gas is diatomic and enters the cylinder at 25°C, determine the maximum compression ratio of the engine.

- Does the entropy increase for a Carnot engine for each cycle?arrow_forwardIs it possible for a system to have an entropy change if it neither absorbs nor emits heat during a reversible? transition? What happens it the process is irreversible?arrow_forwardA certain gasoline engine has an efficiency of 30.0%. What would the hot reservoir temperature be for a Carnot engine having that eficiency, if it operates with a cold reservoir temperature of 200°C?arrow_forward
- The energy output of a heat pump is greater than the energy used to operate the pump. Why doesn't this statement violate the first law of thermodynamics?arrow_forwardIn an isochoric process, heat is added to 10 mol of monoatomic ideal gas whose temperature increases from 273 to 373 K. What is the entropy change of the gas?arrow_forwardWhich of the following is true for the entropy change of a system that undergoes a reversible, adiabatic process? (a) S 0 (b) S = 0 (c) S 0arrow_forward
- (I) What is the change in entropy of 320 g of steam at100°C when it is condensed to water at 100°C?arrow_forward(I) 1.0 kg of water is heated from 0°C to 100°C. Estimatethe change in entropy of the waterarrow_forward(II) 1.0 kg of water at 35°C is mixed with 1.0 kg of water at45°C in a well-insulated container. Estimate the net changein entropy of the systemarrow_forward
- () One mole of monoatomic ideal gas is initially at pressure P and volume V. The gas then undergoes a three-stage cycle consisting of the following processes: -2 P↑ Po To 1 2 To Vo To 2V0 The corresponding P-V diagram is shown above.arrow_forward. (I) What is the change in entropy of 1.00 m3 of water at 0°C when it is frozen to ice at 0°C?arrow_forward(II) A 2.8-kg piece of aluminum at 28.5°C is placed in 1.0 kgof water in a Styrofoam container at room temperature(20.0°C). Estimate the net change in entropy of the system.arrow_forward
