The next several questions are all for one problem of putting a hot piece of metal into a coffee cup of cold water and finding the final temperature. The equation that will be used starts with –q(hot) = q(cold). Which says the coffee cup does not absorb heat, and the heat lost by the hot metal is equal in magnitude, and opposite in sign, to the heat gained by the cold water. Each of these q will be replaced with what? Select one: a. the mass times the specific heat capacity times the final temperature b. the mass of the object c. the mass times the specific heat capacity times the initial temperature d. none of these e. the mass times the specific heat capacity times the change in temperature f. the mass times the specific heat capacity
