Chapter 20: Problem 24

The burning of fuel transfers \(4.00 \cdot 10^{5} \mathrm{~W}\) of power into the engine of a \(2000 .-\mathrm{kg}\) vehicle. If the engine's efficiency is \(25.0 \%,\) determine the maximum speed the vehicle can achieve \(5.00 \mathrm{~s}\) after starting from rest.

Short Answer

Expert verified
Total Work = (4.00 * 10^5 W) * 0.25 * 5.00 s = 1.00 * 10^6 J

Step by step solution

01

Calculate total work done by the engine

We know that the power is the rate at which work is done. We can find the total work done, considering the engine efficiency, using the formula: Work = Power 脳 Efficiency 脳 Time Plug in the given values, and calculate the work done: \(\text{Work} = 4.00 * 10^{5} \text{W} * 0.25 * 5.00 \text{s}\) Calculate the total work done:

A heat engine consists of a heat source that causes a monatomic gas to expand, pushing against a piston, thereby doing work. The gas begins at a pressure of \(300 . \mathrm{kPa}\), a volume of \(150 . \mathrm{cm}^{3}\), and room temperature, \(20.0^{\circ} \mathrm{C}\). On reaching a volume of \(450 . \mathrm{cm}^{3}\), the piston is locked in place, and the heat source is removed. At this point, the gas cools back to room temperature. Finally, the piston is unlocked and used to isothermally compress the gas back to its initial state. a) Sketch the cycle on a \(p V\) -diagram. b) Determine the work done on the gas and the heat flow out of the gas in each part of the cycle. c) Using the results of part (b), determine the efficiency of the engine.

Consider a system consisting of rolling a six-sided die. What happens to the entropy of the system if an additional die is added? Does it double? What happens to the entropy if the number of dice is three?

1 .00 mole of a monatomic ideal gas at a pressure of 4.00 atm and a volume of \(30.0 \mathrm{~L}\) is isothermically expanded to a pressure of 1.00 atm and a volume of \(120.0 \mathrm{~L}\). Next, it is compressed at a constant pressure until its volume is \(30.0 \mathrm{~L}\), and then its pressure is increased at the constant volume of \(30.0 \mathrm{~L}\). What is the efficiency of this heat engine cycle?

The number of macrostates that can result from rolling a set of \(N\) six-sided dice is the number of different totals that can be obtained by adding the pips on the \(N\) faces that end up on top. The number of macrostates is a) \(6^{N}\) b) \(6 N\) c) \(6 N-1\). d) \(5 N+1\).

One of your friends begins to talk about how unfortunate the Second Law of Thermodynamics is, how sad it is that entropy must always increase, leading to the irreversible degradation of useful energy into heat and the decay of all things. Is there any counterargument you could give that would suggest that the Second Law is in fact a blessing?
