Assume you are measuring the specific heat of a sample of originally hot metal by using a calorimeter containing water. Because your calorimeter is not perfectly insulating, energy can transfer by heat between the contents of the calorimeter and the room. To obtain the most accurate result for the specific heat of the metal, you should use water with which initial temperature
(a) slightly lower than room temperature
(b) the same as room temperature
(c) slightly higher than room temperature
(d) whatever you like because the initial temperature makes no difference.
