Q.7Can there be a time-temperature graph as follows? Justify your answer

(iv)

(iv) Yes, it is possible i.e. same temperature at different time  is possible.

Q. 7Can there be a time-temperature graph as follows? Justify your answer.

(iii) No,this type of graph is not possible because different temperature at same time are not posiible.
