(a) In a crash test, two luxury cars travel directly toward each other, each moving at a speed of 25.0 m/s. They collide head-on and stick together. Both have a mass of 2.40 x 103 kg. The air surrounding the two cars has a temperature of 25°C. What is the change inentropy (in J/K) of the air surrounding the two cars as a result of the collision? (Ignore any energy carried away from the collision by sound. Assume the time it takes for the internal energy to dissipate as heat is negligible.)J/K(b) What If? A car with the same mass and moving with the same speed as above collides head-on with a bus, also moving at the same speed, but with a mass of 8.64 x 10° kg. The two vehicles stick together after the collision. What is the change in entropy (in J/K) ofthe surrounding air immediately after the collision?J/K(c) For the collision in part (b), what is the change in entropy (in J/K) of the surrounding air from the point just after the collision to the point where the combined wreckage skids to a stop?J/K

The Sun radiates energy at the rate of 3.80 ✕ 1026 W from its 5500°C surface into dark empty space (a negligible fraction radiates onto Earth and the other planets). The effective temperature of deep space is −270°C. (Due to the sensitive nature of the calculations, use T(K) = T(°C) + 273.15. ) (a) What is the increase in entropy (in J/K) in one day due to this heat transfer?
