Question

3) Thermal Expansion James Bond is in a tight situation. He has to place a 10.00 mm diameter spherical Tungsten ball into a circular hole in a plate of Molybdenum to stop a nuclear Armageddon. The problem is that the hole is only 9.988 mm diameter. All James has is a special pen that Q gave him that can either heat or cool the plate and rod to a particular temperature, but it will only work once for the precise temperature that the pen is programmed to. In addition, both the W ball and the Mo plate must be heated at the same time. What temperature should he program into the pen? Assume that the initial temperature is 25°C. Remember, if he chooses the wrong temperature, the World will be destroyed.

Explanation / Answer

THE TEMPERATURE SHOULD BE 2610 DEGREE C. BECAUSE IN THIS CASE LOW MELTING METAL MOLYBDENUM MELTING POINT IS 2610 DEG.C. SO THE SAME TEMPERATURE SHALL BE PROGRAMMED IN THE PEN.
