Question

Heat (Q) is supplied to a solid to raise its temperature (T) across its melting point (TM) and boiling point

(TB). Which of the following graphs correctly represents the relation between heat supplied and temperature?​

Answer 1

Option C) is the correct graph.

Sequence of events followed while heating a solid:

• With application of heat, the temperature of the solid increases.

• After reaching the melting point , the temperature remains constant during transition of the phase from solid to liquid.

• Again, with increase in applied heat the temperature of the liquid goes on increasing until it reaches the boiling point.

• After reaching the boiling point, the temperature again becomes constant during phase transition from liquid to gas.

• That is why we see constant temperature at $T_{M} \:and\: T_{B}$.

Hope It Helps.

Answer:

its so helpful.bcz its gives the correct concept about this que.
