# Can there be a time-temperature graph as follows? Justify your answer

**Solution:**

We cannot have different temperatures at the same time.

(i) This can be a time-temperature graph, as the temperature can increase with the increase in time.

(ii) This can be a time-temperature graph, as the temperature can decrease with the decrease in time.

(iii) This cannot be a time-temperature graph since different temperatures at the same time are not possible

(iv) This can be a time-temperature graph, as the same temperature at different times is possible.
