1 kg of iron at 100^(@)C melts more ice ...

1 kg of iron at `100^(@)C` melts more ice than 1 kg of lead at `100^(@)C`. Explain why.

Text Solution

Verified by Experts

Specific heat of iron is more than that of lead. Hence, for the same fall in temperature, iron supplies more heat to the ice than lead of the same mass does. Hence, iron melts relatively more ice.
