The statement is true: The temperature of both liquids increases by the same amount.
The temperature increase in a substance depends on the amount of heat added to it, which is determined by both the power of the heater and the duration of heating. In this case, both liquids experience the same temperature increase, and the masses are equal. However, the heating times are different: 100 seconds for Liquid 1 and 200 seconds for Liquid 2.
Since the temperature increase is the same for both liquids, ΔT is constant. Therefore, the heat added is directly proportional to the product of mass and specific heat capacity. If the masses of the two liquids are equal and the specific heat capacities are the same, then the total heat added to both liquids will be the same, even though the heating times are different.
