Thermodynamics Problems

v The problems below are based on the principles and formulas discussed in the coursework- In this assignment we will use metric units; here is a short summary of these units: Force is measured in Newtons (N) Volume is measured in cubic meters (m3) Work and Energy are measured in Joules (J) 1 Joule = 1 Newton‘meter Entropy is measured in Joules per Kelvin (J/K) Be sure to show all of your work- If you write down the formula and the numbers you used I can give partial credit even if the answer is wrong- If you just write the answer you will not get full credit and if the answer is wrong you will get no credit- 1- What type of measuring device relies on Zeroth's Law and how does it do this? 2- The temperature outside is 0 degrees Fahrenheit- What is the temperature in Kelvin? 3- An isolated system absorbs a heat transfer of 45J and performs 20 J of work- What is the internal energy of the system? 4- An isolated system contains some amount of internal energy. If 5 J of heat are transferred into the system, but the internal energy remains the same, how much work must be done by the system? 5- How much work is done by a jet engine that exerts 245 N of force over a distance of 1 km? 6- A gas maintains a constant pressure of 45 mm while being heated- The resulting change in volume is 0-78 m3- What is the work done by the gas? 7- The same gas in problem 6 had an internal energy of 85 J and a final volume of 2 m3- What is the enthalpy (H) of the gas? 8- The combustion process inside a jet engine creates 450 J of heat and does 110 J of work spinning a turbine shafl- What is the change in specific enthalpy of the gas? 9- Through an irreversible process, object A transfers 96 J of heat to object 8. The resulting temperature of the system is 456 K- What is the entropy of the system?
