Some people claim that the theory of evolution violates the second law of thermodynamics, since that theory holds that order develops out of disorder, corresponding to a decrease in entropy. This claim
A. if incorrect, would mean that the theory of evolution must be true.
B. is incorrect; the second law says only that the total entropy in a closed system increases.
C. is correct, thereby disproving the theory evolution.
D. None of these choices are correct
Answer: B

A hot-wire anemometer consists of a 5-mm-long, 5-?m-diameter platinum wire. The probe is operated at constant current of 0.03 amp. The electrical resistivity of platinum is 17 ??-cm at 20°C and increases by 0.385% per °C. (a)If the voltage across the wire is 1.75 volts, determine the velocity of the air flowing across it and the wire temperature if the free-stream air temperature is 20°C. (b)What are the wire temperature and voltage if the air velocity is 10 m/s? Neglect radiation and conduction heat transfer from the wire.
GIVEN • A hot wire in air • Wire diameter (D) = 5 m = 5 × 10–6 m • Wire length (L) 5 mm = 0.005 m • Current (I) = 0.03 A (constant) • Electrical resistivity (rel) = 17 W cm = 17 × 10–8 W m at 20°C and increases 0.385% per °C. • Air temperature (T?) = 20°C FIND (a) The air velocity (U?) and the wire temperature (Tw) if the voltage across the wire (Vel) =1.75V (b) The wire temperature (Tw) and voltage (Vel) if the air velocity (U?) = 10 m/s ASSUMPTIONS • Radiative heat transfer is negligible • Variation of Prandtl number with temperature id negligible PROPERTIES AND CONSTANTS Thermal conductivity (k) = 0.0251 W/(m K) Kinematic viscosity (?) = 15.7 × 10–6 m2/s Prandtl number (Pr) = 0.71 At 90°C: Pr = 0.71

The data points on this graph represent the measured spectrum of the cosmic microwave background, while the solid curve represents a theoretically calculated thermal radiation spectrum for a temperature of 2.73 K. What is the significance of the near-perfect match between the data and the theoretical spectrum?
A) It shows that the cosmic microwave background has a thermal radiation spectrum, just as the Big Bang theory predicts it should. B) It shows that all objects in the universe emit thermal radiation. C) It tells us the average temperature of gas in the Milky Way Galaxy. D) It demonstrates that the universe must contain more dark matter than ordinary matter.
