Indefinite integral: The indefinite integral of a function f(x) is an anti-derivative. It is a function F(x) whose derivative is f(x). You always add an unknown constant to the indefinite integral because the derivative of F(x) plus any constant is the same as the derivative of F(x). With an indefinite integral there are no upper and lower limits on the integral here, and what we'll get is an answer that still has x's in it and will also have a Gas constant.

Definite integral : The definite integral of f(x) between two limits a and b is the area under the curve from x = a to x= b. It is a number, not a function, equal to F(b) - F(a).

A definite integral has upper and lower limits on the integrals, and it's called definite because, at the end of the problem, we have a number - it is a definite answer.

For example, a definite integral of a velocity function gives the accumulated distance over the period. You should also be growing more comfortable with how the units work – for example, integrating meters per second with respect to seconds gives meters.Your job is to find an article that refers to a definite integral. It is possible that you will be able to find an explicit mention of a definite integral. Much more likely, though, the definite integral will be implied...
