> Two pots are identical, except that in one case the flat bottomis aluminum and in the other it is copper. Each pot contains the sameamount of boiling water and sits on a heating element that has a temper-ature of 155 °C. In the aluminum pot, the water boils away completelyin 360 s. Concepts: (i) Is the heat needed to boil away the water in thealuminum-bottom pot less than, greater than, or the same as the heatneeded in the copper-bottom pot? (ii) One of the factors in Equation 13.1that influences the amount of heat conducted through the bottom of eachpot is the temperature difference AT between the upper and lower surfacesof the pot's bottom. Is this temperature difference for the aluminum-bottompot less than, greater than, or the same as that for the copper-bottompot? (iii) Is the time required to boil away the water completely in the*46.copper-bottom pot less than, greater than, or the same as that required forthe aluminum-bottom pot? Calculations: Find the time it takes the waterin the copper-bottom pot to boil away completely.

Two water bottles X and Y have the same mass (m) and very similar size and shape but are made from different materials (Mx and My respectively) at room temperature. The same amount of boiling water is put into X and Y, and then both bottles are closed with screw caps. After 5 minutes, the temperature of water in bottle X is higher than the water in bottle Y. We may then conclude that (with an explanation): (a) Mx has higher specific heat and the water in X has lower internal energy. (b) Mx has lower specific heat and the water in Y has higher internal energy. (c) My has lower specific heat but the water in X and Y have the same internal energy. (d) My has higher specific heat but the water in X has higher internal energy. (e) My and My have the same specific heat and the water in X and Y have the same internal energy.
