Complete the assignment below using additional paper if needed. A hard copy of all work must mitted in class on the indicated due date. To receive credit, all work must be shown. Partial credit is given generously for any form of attempt, but blank answers get no points. Working with classmates is encouraged, but all work must be submitted on your own paper. 1. Define temperature. Name the four scales used to measure temperature. 2. Fill in the table below with the appropriate temperatures for water. Kelvin Celsius Rankine Fahrenheit Boiling Freezing Absolute Zero 3. Convert the following temperatures in Fahrenheit to Celsius. a. -40F b. OF C. 32F d. 45F e. 72F f. 100F g. 212F 4. Convert the following temperatures in Celsius to Fahrentheit. a. -40"c b. o'C c. 12"c d. 50'c e. 72"c f. 100"c g. 212 c 5. Name and describe the three ways in which energy can be transferred. Give an example of each. 6. Describe what is meant by the "method of mixtures." How does this relate to the laws of thermodynamics and energy conservation? 7. Find the heat flow in an 8.0 hour period through a 1 meter x 1 meter pane of glass (3mm thick) if the temperature of the inner surface is 20 "C and the temperature of the outer surface is -10 "C. The thermal conductivity of glass is 1 W / m K. B. Put the letter of each phase change next to its corresponding arrow to complete the diagram. a. Melting b. Ionization c. Condensation d. Deposition e. Sublimation f. Freezing g. Vaporization h. Recombination Plasma Gas Enthalpy of system Liquid Solid 9. For each of the 8 phase changes listed in the previous problem, give an example (e.g. ice melts into water). 10. The temperature difference between the area of either side is 10 cm'. If the distance be e distance between these parallel sides is 5 cm, and the thermal conductivity (K) of brass is 120 J/(s m "C), what is the rate of heat transfer from one side to the other per second? . The Louisville and Nashville (L&N) Railroad had 10,400 mi of steel tracks throughout the southeast US when it was bought by the company that would become CSX in the 1980's. Suppose this length is measured at STP (32 "F, 1 atm). During the summer, a blistering heat wave swept through, raising temperatures to 105 *F. Assuming the temperature is the same for the whole region and the coefficient near expansion fo "F, what was the total length in miles of the L&N line in the heat wave? (Note: No unit conversions are required.) 12. How many Joules of heat are required to change 3.5 kg of ice at -15.0 .C to steam at 120 'C? 13. True or False: Entropy must always increase. 4. Describe the motion of a point on a transverse wave relative to the wave's direction of motion. 15. Describe the motion of a point on a longitudinal wave relative to the wave's direction of motion. 16. Define each of the following parts of a wave: a. Amplitude b. peak c. Trough d. Period e. Frequency f. Wavelength g. Rarefaction h. Compression 17. Draw two diagrams: one of a transverse wave and one of a longitudinal wave. Label the parts of the waves using the list of terms above. 18. Describe how the superpositioning of waves leads to constructive and destructive interference. 19. Describe how interference allows noise-canceling headphones to work. Be sure to include the phase shift. 20. A bat uses an ultrasound frequency of 10 MHz to locate a moth. Assume the speed of sound is 340 m/s. a. If the echo returns after 0.25 s, how far away is the moth from the bat? b. If the returning frequency is 10.25 MHz, what is the velocity of the moth? C. Is the moth moving toward or away from the bat? How do you know? 21. The frequency of the sound of a truck on the highway is 85.0 Hz. Assume the speed of sound is 340 mis. a. If the truck is tra quency do you hear? b. If the truck is traveling 27.0 m/s away from you, what frequency do you hear
