38. A bike tire is filled to 115 torr on a normal 20  C day. Later that afternoon, Joe went for a long ride and the tires heated up to 75  C. What will be the new air pressure of the tires?

39. 115 torr = x 293K = 348K

45. 1 atm (760mmHg, 760torr, 101.3kPa) 0  C (273K)

48. -33  C is this value in the Kelvin scale.

54. This amount of heat (in kJ) is released when 18g of water is cooled from 75  C to 20  C. Constant Values: Heat capacity of water: 4.18 J/g  C Heat of fusion: 6.0 kJ/mol Heat of Vaporization: 40.7 kJ/Mol

55. What is -4.14kJ? q = m C ∆T q = (18g) (4.18 J/g o C) (20-75) 1000
