064 Name:

Chart of temp rise
Data from laboratory 064

  1. ___________ Which material more quickly conducted heat, as indicted by temperature, in the first five minutes of measurement, Pb (lead) or brass?
  2. ___________ Which material conducted more overall heat, at least as indicated by temperature, by then end of the measurements at 26 minutes, Pb (lead) or brass?

    In physics, thermal conductivity, k, is the property of a material's ability to conduct heat. For thermal conductivity, higher numbers mean faster rates of heat movement.

  3. ___________ Based on the laboratory data presented in the chart above, which material has the higher heat conductivity?
  4. ___________ Brass has a heat conductivity of 109 W/m K. Lead has a heat conductivity of 34.7 W/m K. Does the data support these theoretic values?
  5. Why?


  6. _________°C What is the temperature of a mix of melting ice and water in Celsius?
  7. _________°C What is the temperature of melting solid coconut oil in Celsius?
  8. _________°C What is the typical daily air temperature in Pohnpei in Celsius?
  9. _________°C What is the temperature of the healthy living human body in Celsius?
  10. _________°C What is the temperature of a boiling water in Celsius?
  11. The temperature in Kolonia usually never drops below the freezing point of ______________________.
