Boiling water is changing into steam. Under this condition,the specific heat of water is

An ice cube at temperature $-20^oC$ is kept in a room at temperature $20^oC$. The variation of temperature of the body with time is given by

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

An experiment takes $10\, minutes$ to raise the temperature of water in a container from $0\,^oC$ to $100\,^oC$ and another $55\, minutes$ to convert it totally into steam by a heater supplying heat at a uniform rate. Neglecting the specific heat of the container and taking the specific heat of water to be $1\, cal/g\,^oC$,the heat of vaporization according to this experiment will be ........ $cal/g$.

What is latent heat? Explain with an example.

Steam at $100\,^{\circ}C$ is more dangerous than the same mass of water at $100\,^{\circ}C$ because the steam
