The substance which does not expand on going from liquid

Home » Chemistry » Chemistry miscellaneous » Question

The substance which does not expand on going from liquid state to solid state is

1. Water
2. Cast-iron
3. Aluminium
4. Type metal

Correct Option: D

In printing, type metal (sometimes called hot metal) refers to the metal alloys used in traditional type founding and hot metal typesetting. Lead is the main constituent of these alloys. Antimony and tin are added to make the character produced durable and tough while reducing the difference between the coefficients of expansion of the matrix and the alloy. Pure metal melts and solidifies in a simple manner at a specific temperature. This is not the case with alloys.
