As part of an experiment, you filled a weighted piston-cylinder device as shown in Figure 2 with 120 grams of Refrigerant-134a until the pressure gauge reads 100 kPa and temperature is measured at -20°C. You then applied heat to the bottom of the piston-cylinder device until the temperature is 100°C. Calculate the change in volumes of the R-134a due to the heating process.
