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 50C, 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–are the same size, but made of different materials. will not melt at temperatures about 100C. release thermal energy quickly to the environment. are made of metals, since they conduct heat.
