A student wishes to investigate how the material of which an object is made affects how the object changes temperature. The student will heat objects to a temperature of 50°C, then see how long it takes the objects to cool down to room temperature. For this investigation, it is most important that the student use objects that -
A. are the same size, but made of different materials.
B. will not melt at temperatures above 100°
C. release thermal energy quickly to the environment.
D. are made of metals, since they conduct heat.
