Each of the following incompressible substances are heated by increasing its internal energy by 1500 kJ, with the purpose of increasing the temperature from 300 K to 500 K. Determine the mass of each substance which will result in this temperature increase:
(a) aluminum (c = 0.90 kJ/kg-K)
(b) gold (c = 0.13 kJ/kg-K)
(c) zinc (c = 0.39kJ/kg-K)
(d) gasoline (c = 2.08 kJ/kg-K).
Given: ?U = 1500 kJ; T1 = 300 K; T2 = 500 K
What will be an ideal response?
(a) Aluminum: c = 0.90 kJ/kg-K
mAl = 8.33 kg
(b) Gold: c = 0.13 kJ/kg-K
mAu = 57.7 kg
(c) Zinc: c = 0.39 kJ/kg-K
mZn = 19.2 kg
(d) Gasoline: c = 2.08 kJ/kg-K
mgas = 3.61 kg

Determine the toll to yield the highest revenue for part a.
A bridge has been constructed between the mainland and an island. The total cost (excluding tolls) to travel across the bridge is expressed as C = 50 + 0.5V, where V is the number of veh/hr and C is the cost/vehicle in cents. The demand for travel across the bridge is V ? 2500 ?10C . What will be an ideal response?
