Question 18: A student heats some amount of tap water in a calorimeter to a temperature of nearly 50ºC above the room temperature. He then records the temperature of this water as it is cooling down at regular intervals of 2 minutes each. He tabulates his observations as follows :
Time (in minutes) →0246810
Temperature (in ºC) →t1t2t3t4t5t6
He is likely to observe that :
(1) (t1 − t2) > (t3 − t4) > (t5 − t6)
(2) (t1 − t2) = (t3 − t4) = (t5 − t6)
(3) (t1 − t2) < (t3 − t4) < (t5 − t6)
(4) (t1 − t2) < (t3 − t4) > (t5 − t6)
