Bismuth has the greatest heat capacity among iron, tin, and bismuth. This is because heat capacity is directly related to the specific heat capacity of a substance, which is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. Bismuth has the highest specific heat capacity among these three metals, indicating that it can absorb more heat energy per unit mass compared to iron and tin. Therefore, bismuth has a greater heat capacity.
