Write a hypothesis for Part I of the lab, which is about the effect of mass on the ability of an object to absorb or
release thermal energy. Use the format of "if ... then ...
because ..."and be sure to answer this part of the
lesson question: "How does mass affect thermal energy
transfer?"

A248-g piece of copper is dropped into 390 ml of water at 22.6 °c. the final temperature of the water was measured as 39.9 °c. calculate the initial temperature of the piece of copper. assume that all heat transfer occurs between the copper and the water. remember, the density of water is 1.0 g/m
