Calculations
A. Calculate the theoreticalspeed of sound (v):
v = 331.4 + 0.6TC( m/s)
• 331.4 m/s is the speed of sound at 20oC
• TC is the temperature of air during testing measured in Celsius
B. Calculate the percent error of your experimentally derived value:
C. Is sound a longitudinal or transverse wave?
D. What is the physical concept behind the "pitch" of a sound and what is the SI unit for it?
E. What is the physical concept behind "intensity" of a sound and what is the SI unit for it?

Question:
A. Howis specific heat of a metal compared with water's specific heat? (Check the table for specific heats from the lab manual or the textbook) Are your results reflecting your answer?
B. What are the SI units for:
Heat
Temperature
C. How much is the amount of heat "gained"by the waterin your experiment? Write the equation and then the calculations for just one metal.
D. What are possible sources of errors in this experiment?
