Soldering of two metals is possible because of the property of :

A Viscosity
B Osmosis
C Cohesion
D Surface tension

Correct Answer: Cohesion

Soldering is the process of joining two metals by the use of a solder alloy, and it is one of the oldest known joining techniques. It is possible because of the property of cohesion, the interaction between adjacent parts of the same body and as acting throughout the interior of substance. Soldering leads to alloy formation at the layer between two metals.
