$A$ 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?

$A$ substance of mass $m \ kg$ requires a power input of $P \ W$ to remain in the molten state at its melting point. When the power is turned off,the substance completely solidifies in time $t \ s$. The latent heat of fusion of the substance is

$A$ quantity of heat required to change the unit mass of a solid substance,from solid state to liquid state,while the temperature remains constant,is known as

Write the unit and dimensional formula for latent heat. On what factors does the value of latent heat depend?

Why do we get burnt more by steam than by boiling water at the same temperature?

During an experiment,it takes $10 \text{ minutes}$ to raise the temperature of water from $0 \text{ °C}$ to $100 \text{ °C}$,and then it takes another $55 \text{ minutes}$ for the water to completely convert into steam. The value of the latent heat of vaporization is ....... $\text{cal/g}$.
