A typical gasoline (β=0.00095/°C)  tank can hold 65 liters (~17 gallons). At the gas station, the storage tank is underground and is maintained at a temperature of 50.0°F. On a hot day at 103.0°F you fill your empty tank. (a) What is the equivalent temperature difference in °C? A typical gasoline (β=0.00095/°C)  tank can hold 65 liters (~17 gallons). At the gas station, the storage tank is underground and is maintained at a temperature of 50.0°F. On a hot day at 103.0°F you fill your empty tank. (c) How much gas should you put in your car on this hot day at so that it will fill (not overfill) the tank when it expands to 103.0°F?

The diagram presented represents a thermodynamic process experienced by 27.5mmol (millimoles) of a monatomic ideal gas. The volume axis is divided into equal increments υ0=777cm3 while the pressure axis is divided into equal increments p0=0.301atm. Part (a)  How much work, in joules, does the gas perform on its environment during the thermodynamic process represented in the diagram?  Part (b)  What is the change, in joules, of the internal energy of the gas during the process represented in the diagram?  Part (c)  How much heat, in joules, is absorbed by the gas during the process represented in the diagram?

A rigid tank filled with water is divided into two chambers by a membrane. The membrane is a perfect insulator and there is no heat transfer between the chambers. The volume of the water in chamber A and chamber B is VA = 1 m² and Vg = 4 m³, respectively. Initially (state 1) chamber A contains water at a temperature of 150 °C and a pressure of 350kPa. Chamber A also contains a plate of nickel with a mass of myi = 20 kg that is always in thermal equilibrium with the water. Chamber B contains 40 kg of water at a temperature of 80 °C. The membrane ruptures and heat transfers between the tank and its surroundings such that the water inside the tank reaches a uniform state, with a final temperature, T2, of 100°C. The specific heat of nickel is CpNi = 0.44 kJ/kg-K. c) Determine the pressure and specific internal energy of the water at the final state. (ie. P, and uz) d) Determine total heat transfer (between the tank and its surroundings) during the process. (ie. 1Q2) A В (Water) (Water)…
