If the following weights have masses of 2, 4, 6 and 8 kg,
respectively, and they are at the same temperature, which one
will transfer more heat if they are all placed in cold water to
cool down? Explain.

Unit is calorimetry

8 kg mass

Explanation:

As we can see in the image the weight of mass 8 kgs has a large surface area as compared to the surface area of other masses. In general, it has been observed that a wide surface area has more surface particle for heat conduction. Hence, the rate of heat transfer is directly proportional to the surface area of heat conducting surface. Thus, the larger the surface area, the faster is the rate of heat conduction.

Hence, weight of mass 8Kg wil transfer heat a fast rate.
