1. Data and 2. procedures or functions

Explanation:

The object in an object oriented programming comprises of data and the procedures, The data describes the object, and the procedures explains what that particular object can do. And that is a function and nothing else. We declare a data, and procedure or function. We then initialize the data through constructor. And finally we does the operation like here its change heat by defining a function for it. A function is first declared, then defined and finally called for getting the desired output.
