When a 10.0 g sheet of copper is initially at 22.0 degrees Celsius is placed on a 20.0 g sheet of aluminum initially at 75.0 degrees Celsius, what is the final temperature of the the two metals (assuming no heat is lost to the surroundings?) Ccu 0.385 J/gC Cal 0.900 J/gCThanks I will award best explanation to find it. I know the answer is 65.7 degrees Celsius just don‘t know how
The amount of heat energy before the amount of heat energy afterwards (since none is lost, and none is converted to other forms). Next the final temperature is the same for both metals. Remember to use kelvin or Rankine units for all thermodynamic calcuclations. m1 * cp1 * T1 + m2 * cp2 * T2 (m1 * cp1 + m2 * cp2) * T3 Just insert your numbers and you have T3.
