17. condensation by product of cooling
18. 3 main modes 1)conduction
2)convecti

3)radiation
19. convection enerfy transfer through fluid motion
Ex) blowing on hot soup to cool it down,
exchanging energy
20. conduction is the process by which energy is transmitted
through
collisions between neighboring molecules
ex) fiberglass insulation, frying pan heated up by a
stove
21. radiation emission or transmission of energy in the form of
waves
through space or through material medium
22. wet bulb used to estimate the effect of temperature,
globe humidity, wind speed (wind chill), and visible and
temperature infrared radiation (usu- ally sunlight) on humans;
determine appropriate exposure levels to high
temperature
23. WBGT .7Tw+.2Tg+.1Td
24. Tw Natural wet-bulb temperature (combined with
dry-bulb temperature indicates humidity)
25. Tg Globe thermometer temperature (measured with
