Unformatted text preview: Solutions for Homework 1 Chapter 17 Problems 28. Use the relationships T K ( ) = T C ( ) + 273.15 and T K ( ) = 5 9 T F ( ) ! 32 " # $ % + 273.15 . ( a ) T K ( ) = T C ( ) + 273.15 = 66 + 273.15 = 339 K ( b ) T K ( ) = 5 9 T F ( ) ! 32 " # $ % + 273.15 = 5 9 92 ! 32 " # $ % + 273.15 = 306K ( c ) T K ( ) = T C ( ) + 273.15 = ! 55 + 273.15 = 218 K ( d ) T K ( ) = T C ( ) + 273.15 = 5500 + 273.15 = 5773.15K ! 5800K 50. The ideal gas law can be used to relate the volume at the surface to the submerged volume of the bubble. We assume the amount of gas in the bubble doesnt change as it rises. The pressure at the submerged location is found from Eq. 13-6b. PV = nRT ! PV T = nR = constant ! P surface V surface T surface = P submerged V submerged T submerged ! V surface = V submerged P submerged P surface T surface T submerged = V submerged P atm + " gh P atm T surface T submerged = 1.00cm 3 ( ) 1.013 ! 10 5 + 1.00 ! 10 3 kg m 3 ( ) 9.80m s 2 ( ) 37.0m ( ) " # $ % 1.013 ! 10 5 ( ) Pa...
