- A 1 500-kg car is moving at 20.0 m/s. The driver brakes to a stop. The brakes cool off to the temperature of the surrounding air, which is nearly constant at 20.0°C. What is the total entropy change?The temperature at the surface of the Sun is approximately 5,600 K, and the temperature at the surface of the Earth is approximately 291 K. What entropy change of the Universe occurs when 4.50 103 J of energy is transferred by radiation from the Sun to the Earth? ____________ J/KOn a hot summer day, 2.00 x 106 J of heat transfer into a parked car takes place, increasing its temperature from 33.0°C to 45.2°C. What is the increase in entropy (in J/K) of the car due to this heat transfer alone? J/K
