  27. Basics$100Answer What is meant by thermal contact? Heat energies can be exchanged. Back to Jeopardy

  28. Basics$200Answer What is meant by thermal equilibrium? Both objects are at the same temperature. Back to Jeopardy

  29. Basics$300Answer Name the three temperature scales that are in common use. Give the boiling point and the freezing point of water, and absolute temperature in each scale. Back to Jeopardy

  30. Basics$400Answer What does Temperature measure? The average kinetic energy of atoms and molecules in a substance. K.E. ATOM = ½mvAVE² = ½kBT where T in Kelvin Boltzmann’s Constant kB =1.38*10-23 J/K Back to Jeopardy

  31. Constants$100Answer What is Avogadro’s number? NA = 6.02 *1023 units 1 mole contains Avogadro’s number. Back to Jeopardy

  32. Constants$200Answer What is the Boltzmann’s Constant? kB =1.38*10-23 J/K Back to Jeopardy

  33. Constants$300Answer What is the Universal Gas Constant? R = NAkB = 8.31 J/(mole*K) Back to Jeopardy

  35. Heat $100Answer What is Heat? The form of energy that is transferred between two substances because they have different temperatures. Back to Jeopardy

  36. Heat $200Answer What is Internal energy? The sum of the kinetic and potential energies of all the atoms and molecules in a substance. Back to Jeopardy

  37. Heat $300Answer What is meant by thermal expansion? The size of an object will change due a temperature Usually, increasing temperature but cause an increase in size. L = LOT where  = thermal coefficient in 1/OC Back to Jeopardy

  38. Heat $400Answer Temperature at which water has the greatest density. 4 OC The density of water decreases as water cools from 4OC to 0OC. Back to Jeopardy

  39. Transfer $100Answer What are the 3 methods of Heat Transfer? Conduction Direct (Needs physical Contact) Convection Occurs in fluids Radiation Carried by photon Back to Jeopardy

  40. Transfer $200Answer Firewalkers" step on the hot ashes and coals from a wood fire without getting their feet burned. How might this be possible? The ashes are poor conductors of heat. H = kAT/L where k = thermal conductivity coefficient in Watts/(m*K) Back to Jeopardy

  41. Transfer $300Answer A wood stove in the corner of a cabin causes the entire cabin to become heated. This is an example of convection. Back to Jeopardy

  42. Transfer $400Answer Which mechanism of heat transfer will work in a vacuum? Radiation Power = AT4  = 5.67*10-8 Watts/(m²*K4)  = emissitivity constant is between 0 (reflector) & 1 (absorber) Back to Jeopardy

  43. Laws $100Answer State the zeroth law of thermodynamics. If Body A in in thermal equilibrium with Body B & If Body B in in thermal equilibrium with Body T then Body A in in thermal equilibrium with Body T. Back to Jeopardy

  44. Laws $200Answer State the first law of thermodynamics. Conservation of energy Internal Energy of a system = Q – Work done by a system OR Internal Energy of a system = Q + Work done on a system Back to Jeopardy

  45. Laws $300Answer State the second law of thermodynamics. There are no perfect heat engines. Back to Jeopardy
