Cards in this deck (45)

  1. 1worktransfer of energy
  2. 2closed systemenvironment cannot contribute matter to it
  3. 3isolated systemenvironment cannot contribute either matter or energy to it
  4. 4molecular level random motionTemperature T (kelvins)
  5. 5HeatQ
  6. 6Heattransfer of thermal energy (joules)
  7. 7Q> 0energy into the system
  8. 8Q<0energy out of the system
  9. 9thermal energyextensive (depends on amount)
  10. 10temperatureintensive property (does not depend on the amount of the substance)
  11. 11temperaturestate variable
  12. 12zeroth law of thermoequal heat transfer between objects of same temp (not net heat transfer)
  13. 13movement of thermal energy form one point to anotherconduction
    convection
    radiation
  14. 14conductiontransfer of thermal energy (stove to yr hand)
  15. 15state variablestemperature, pressure, volume, moles, entropy
  16. 16conductionatoms of hot skillet bump into atoms of hand making them vibrate more and heating them up
  17. 17conduction raterate at which materials conduct heat
  18. 18convectionthink candle
  19. 19convectionheat transferred away from the flame
    air around flame warms, expands, become less dense than the cooler surrounding air
  20. 20radiationabsorption of energy of light waves
  21. 21first law of thermototal energy of universe constant
  22. 22delta E = Q-Wq positive when heat into system
    w negative when work done by the environment on the system
  23. 23ideal gas sealed in container with piston on topKE=PE=0
    only form of energy is thermal energy
    einternal = ethermal
    E=Q-W
  24. 24piston problemE=Q-W
    E = work by system
    W = heat out of system
  25. 25pistoninternal energy proportional to temp
  26. 26pistonW=PdeltaV
    w=pressure x change in volume
  27. 27isobaricconstant pressure
    w=pv
  28. 28isochoricconstant volume
    W=o
    E=Q
  29. 29isochoricno work done
  30. 30isothermal processheat allowed to pass between system and environment so temperature remains constant (P and V because indirectly proportional)
    E=o and Q=W
  31. 31adiabaticne heat transferred (can still have change in temp)
    E=-W
  32. 32constant pressurerequires more heat for an equal change in temp that constant volume
  33. 33E=Q-PVisboaric is e=q+pv
  34. 34Cp=Cv+Radgasdgsdt
  35. 35clockwise graphheat to work
  36. 36free expansionconstant pressure then release it (remove the piston suddenly)
    no work done
  37. 37entropymeasure of disorder
  38. 382nd law of thermoentropy of an isolated system either stays the same of incrases
  39. 39if entropy remains same through a thermodynamic cycleit is reversible
  40. 40in real worldthermodynamic processes are irreversible
  41. 411 m^3= 1000 liters
  42. 42pascalJ/m^3
  43. 43PV diagramif you return to same spot all the state variables return to original value
  44. 44entropystate variable
  45. 45Pv=nRTideal gas law
