Interactne Loemingwan 12.1 provide?? review of the concepts that are important in this problem, During an all t cra session & student heets up ? one-halri ter 0 50 x 10 3 m3 ass Pyre beaker cr cold coree. Initially, the temperature is 18 c ar d the beaker is nled to the brtm A short time later hen the student returns, the temperature has rise volume expension of coffee is the same as thet of water How much coffee (in cubic meters) has spilled out of the beaker? to 93°C, The o emce t of Additional Matoriaila DSecion 12.5

Explanation / Answer

initial volume of the cold coffee is vi = 0.5*10^-3 m^3

coefficient of volume expansion of pyrex glass = Bpyrex = 12*10^-6 /K

coefficient of volume expansion of water = Bwater = 210*10^-6 /K

temperature difference = 93-18 = 75 K

then the amlunt of cofee spilled out is

= vi(Bwater-Bpyrex)*temperature difference

= 0.5*10^-2(210*10^-6-12*10^-6)*75

= 7.425*10^-6 m^3
