Determine the temperature of the thermal equilibrium between the potatoes in water, and the same portion in oil, considering each cases as isolated systems.
In a kitchen there are two identical pots that have been previously heated, one of the pans is filled with 500ml of Water at 100◦C and the other with 500 no of oil at 130◦C. After that, there is more fire that continues to introduce heat to both liquids. In that instant, a person who had cut 300 g of potato into small cubes at a temperature of 25◦C, decides to pour half the amount of potato in boiling water and the other half in burning oil. Knowing that Water density is the 1.00 g / ml; the oil density = 0.87 g / ml; the
Specific heat of water = 4186 J/ kg ·◦C, is the
Oil specific heat = 2000 J/ kg ·◦C is the
Potato specific heat = 5530 J /kg ·◦C
(a) Determine the temperature of the thermal equilibrium between the potatoes in water, and the same portion in oil, considering each cases as isolated systems.
