(A) The process of heating ice from $-10^{\circ}C$ to steam at $100^{\circ}C$ involves several stages:$1$. Heating ice from $-10^{\circ}C$ to $0^{\circ}C$: The temperature rises linearly as heat is supplied.$2$. Melting ice at $0^{\circ}C$: The temperature remains constant at $0^{\circ}C$ while the phase changes from solid to liquid (latent heat of fusion).$3$. Heating water from $0^{\circ}C$ to $100^{\circ}C$: The temperature rises linearly as heat is supplied.$4$. Boiling water at $100^{\circ}C$: The temperature remains constant at $100^{\circ}C$ while the phase changes from liquid to gas (latent heat of vaporization).Therefore, the heating curve must show two linear rising segments separated by a horizontal segment (melting) and followed by another horizontal segment (boiling). Option $A$ correctly represents this sequence.

$A$ block of ice at $-10^{\circ}C$ is slowly heated and converted to steam at $100^{\circ}C$. Which of the following curves represents the phenomenon qualitatively?
