It is well known that two clean glass plates with optically worked flat surfaces adhere to one another when brought into intimate contact. Considerable force is required to separate the plates; in fact, it often happens that their surfaces become damaged during the process. Such adherence is clearly due to molecular cohesion. Similar evidence of cohesion is observed when contact is made between accurately flat, polished surfaces of steel and of steel and glass.
