Im Having issues trying to solve this exercise of Thermodynamics. it already gives me the answer but im not sure how to get to that answer.

**Transcription:** **Problem 3-61** 100 grams of R-134a initially fill a weighted piston-cylinder device at 60 kPa and -20°C. The device is then heated until the temperature is 100°C. Determine the change in the device’s volume as a result of the heating. **Answer:** 0.0168 m³ **Diagram Explanation:** - The diagram shows a vertical, cylindrical container with a piston on top, labeled as a piston-cylinder device. - Inside the cylinder, the substance R-134a is specified with the initial conditions of 60 kPa, -20°C, and 100 grams. - An arrow labeled "Q" is pointing towards the cylinder, indicating the addition of heat to the system. - The piston is weighted, allowing it to move as the volume inside changes due to heating. This setup demonstrates a typical thermodynamic process where a substance within a closed system is subjected to heating, resulting in changes in volume due to temperature increase.
