Answer
(a) The temperature change of object 1 is greater than the temperature change of object 2.
(b) III
Work Step by Step
(a) We know that the object with less mass has a smaller heat capacity and greater change in temperature. Hence, the temperature change of object 1 is greater than the temperature change of object 2.
(b) The correct option is (III). When one object loses heat of magnitude Q, the other gains heat of the same magnitude. We know that mass and temperature change are inversely proportional, hence the smaller object has the greatest temperature change.
