While driving down Business 40 West, you notice that your engine light comes on in the dashboard of your car. Once you get the car to a mechanic, she explains that your 41 lb lead car battery began to melt during the process of the car overheating. If the temperature reached 625 degrees Fahrenheit from 250 degrees Fahrenheit, what was the total amount of heat in this process? PLEASE SHOW ALL WORK AND UNITS

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?
