The forces holding naphthalene crystals together can be overcome when naphthalene is heated to a temperature of 354K resulting in the crystal to melting. These forces are known as?
Explanation
A set is a collection of distinct objects (elements). Notation: A = {1, 2, 3}. ∈ means “belongs to”: 2 ∈ A. ∅ is the empty set. Universal set (U) contains all elements under consideration.
Operations: Union (A ∪ B) contains all elements in A or B. Intersection (A ∩ B) contains elements in both. Complement (A) contains elements in U but not in A.
Venn diagrams visualize set relationships. Overlapping circles show intersection; non-overlapping areas show elements in one set only. Useful for probability, logic, and survey analysis.
