Study temperature -time graph given below: The graph shows heating of ice form -10^(@)C to water at 100^(@)C. Identify the part of the graph which represents the change of state on heating. During change of state where does the absorbed heat energy go? |
|
Answer» Solution :Parts BC and DE of the GRAPH represents the change of state on HEATING. The heat energy SUPPLIED during the change of state is used to overcome the force of attraction between the particles or matter. This heat is known as latent heat. [The heat energy is STORED in water at`0^(@)C` in the form of latent heat of fusion and is stored in steam at`100^(@)C` in the form of latent heat of vaporisation.] |
