| Abstract: | To measure the specific heat of metallic copper more quickly and even better,we suggest herein an experimental arrangement on heating the copper.With somewhat changes in the current procedure,college students should have more training on the use of analytic balance,and complete the measurement better than they used to do.Furthermore,the new experimental design makes the college students understand roughly the concept of extrapolation,which is useful in physical measurement sometimes. |

| Keywords: | specific heat extrapolation analytic balance mixed heating measurement nearadiabatic condition |
