A block of ice at $- 10°C$ is slowly heated and converted to steam at $100°C.$ Which of the following curves represents the phenomenon qualitatively
A solid material is supplied with heat at constant rate and the temperature of the material changes as shown below. From the graph, the false conclusion drawn is:
Explain the process of change in state of matter by heating or cooling it.
The graph signifies
An ice cube at temperature $-20^o C$ is kept in a room at temperature $20^o C$. The variation of temperature of the body with time is given by
