The perfect gas law for air is expressed as: pv= 286 T where p is the pressure, v is the specific volume and T is the temperature at any given state. (i) Define Python functions that implement the above formula. A specific function should return the value of one of the parameters in the given law taking the other parameters as as argurments (6 marks) (ii) Write a test Python program that uses the functions above to determine a desired parameter. Allow the user to select the term to determine as desired. The user should be able to continuously determine the terms of interest within a loop and exit the program when desired. (10 marks)
