Write a function named is_float(s) that takes one argument that is a string. It returns True if string s represents a floating point value and returns False otherwise. You are required to use try-except. The basic concept is to "try" to convert string s to a float and if it succeeds, return True, but if it fails (that is, an exception is raised), return False. Note that float() raises a ValueError exception.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
