2. The verb "estar" is used to express temporary states or conditions, or to indicate the location of someone or something.

In this case, being happy is a temporary state that may change over time. Similarly, you would use "estar" to describe the location of an object: "El libro está en la mesa" (The book is on the table). In this case, the book's location can change.
