When a piece of copper, at a temperature of 256.0 degrees Celsius, is added to 255 grams of water at a temperature of 20.0 degrees celsius, the temperature of the resulting mixture is 24.0 degrees celsius. If the specific heat of copper is 0.385 J/g x degrees celsius, what was the mass of the copper? The specific heat of water is 4.184 J/g x degrees celsius.

Solutions

Expert Solution

heat lose of copper                   =                              heat gain of water

mcT                                      =                               mcT

m*0.385*(256-24)                      =                               255*4.184*(24-20)

m                                                = 47.78g

mass of copper                         = 47.78g >>>>answer

Consider copper from 0 degrees Celsius to 1000 degrees Celsius. The density for copper at 0 degrees is 8.92 g/cm^3. Assume the vacancy formation energy is 0.91 eV/atom and that the volume coefficient of thermal expansion is 3 times the the linear coefficient of thermal expansion. 1) Determine the density change between these two temperatures due to the change in the number of vacancies. Thermal expansion coefficient of copper is 9.3 (10-6 in/(in R))*) OR 16.6 (10-6 m/(m K))
