Question

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.

Objects that are of the same size but made of different materials

Explanation:

The rate it takes the object to cool is equivalent to the rate of heat loss

The rate of heat loss is given by the equation:

dQ/dt = K(T-T₀)

Where T = Temperature of the hot surface

T₀ = Temperature of the surrounding

K = constant

Both K and the rate of heat loss depends on the:

• nature of the surface
• Area of the surface
• Material of the surface of the body

Since the student only wants to know how the material in which the object is made of affects change in temperature, it means only the materials must be varied while other factors such as area and the size of the objects are kept constant.
