Bot which has greater heat capacity---iron, tin, or bismuth? Why do you say this?
Among iron, tin, and bismuth, bismuth has the greatest heat capacity.
Heat capacity measures the amount of heat energy required to raise the temperature of a substance by a certain amount. Bismuth has a specific heat capacity of around 0.123 J/g°C, which is higher than both iron (0.45 J/g°C) and tin (0.23 J/g°C).
Bismuth's larger heat capacity is due to its atomic properties. Bismuth has a lower atomic mass and higher atomic radius compared to iron and tin. These factors contribute to weaker metallic bonding in bismuth, allowing it to more readily absorb and store heat energy.
Therefore, when comparing these three metals, it can be concluded that bismuth has the greater heat capacity.
