Question

Some students performed the following experiment. They took a100 gram piece of copper and placed it in boiling water for a longtime (until it was in thermal equilibrium with the water). Then,they quickly transferred the hot copper into 50 grams of water thatwas initially at 20 ºC. They tracked the temperature of thewater and noticed that it increased up to a maximum temperature of32.5 ºC.. Using this information, determine the specific heatof copper (that is, how much heat energy is needed to increase thetemperature of one gram of copper by one degree Celsius?). Show andexplain all work!!

Explanation / Answer

The energy that heated the water up is equal to the energy thatleft the copper. Ecopper=Ewater m(copper)c(copper)T(copper)=m(water)c(water)T(water) c(copper) =m(water)c(water)T(water)/m(copper)T(copper) c(copper)= 0.3876 J/(g degC)
