Toppr Admin · Accepted Answer

ST-In part PQ- the state is liquid and temperature is decreasing- In part QS there is change of state from liquid to solid- i-e- this stage is freezing- without change in temperature- In part ST- state is solid and temperature is decreasing with time-

$S T$ .
In part $P Q$ , the state is liquid and temperature is decreasing, In part $Q S$ there is change of state from liquid to solid, i.e., this stage is freezing, without change in temperature. In part $S T$ , state is solid and temperature is decreasing with time.
