![]() This is because the total amount of thermal energy depends on the mass of the muffin (that goes as s 3), but the muffin cools off by radiating from its surface area (that goes as s 2). This is all part of the physics rule that says " big things are not like small things." For instance, if you bake a muffin, smaller muffins cool off faster than bigger muffins. So, as the scale increases, the weight increases faster than the strength does. ![]() His strength is proportional to his cross-sectional area-that goes like s 2. His weight is proportional to his volume-so that depends on s 3.
