The graph signifies:

$A$ metallic ball and a highly stretched spring are made of the same material and have the same mass. They are heated so that they melt. The latent heat required:

$A$ solid material is supplied with heat at a constant rate and the temperature of the material changes as shown in the graph. From the graph,the false conclusion drawn is:

The figure given below shows the cooling curve of a pure wax material after heating. It cools from $A$ to $B$ and solidifies along $BD$. If $L$ and $C$ are the respective values of latent heat and the specific heat of the liquid wax,the ratio $L/C$ is

Boiling water is changing into steam. At this stage,the specific heat of water is

The portion $AB$ of the cooling curve representing the state of matter denotes:
