Water Salinity modifications 1. 2 Modify the program so that it converts and prints the new temperature in degrees Centigrade. 3.Suppose that the data used with the program contained values with the degrees in Centigrade. Would the program need to be changed? Explain. It does not need to be changed since the equation is same. 4. Open Jet 1. 2. 3.
