Answer: At this rate, it would take less than 10 minutes for the temperature of the liquid to rise 52° C.
Step-by-step explanation:
Given: The graph shows the temperature of a liquid that is being heated during an experiment.
From the graph , we can see the the line is going up from left to the right.
Therefore, the temperature of liquid is increasing at a constant rate [as the line is at same distance from temperature axis and time axis].
In 6.5 minutes the rise in temperature= 26°C
Therefore in 1 minute , the change in temperature= \(\frac{26}{6.5}=4^{\circ}\)
Now in quarter hour(15 minute), temperature=\(4\times15=60^{\circ}C\)
To rise in temperature by 52°C, time taken=\(\frac{52}{4}=13\ minutes\), which is greater than 10 minutes.
Thus fourth statement is incorrect about the graph.
