**Thermodynamics: property tables HELP!!**

## Homework Statement

1 kg of R-134a fills a 0.14m^3 weighted piston cylinder device at a temperature of -26.4C. The container is now heated until the temp is 100C.

Determine the final volume.

## The Attempt at a Solution

So the boiling point is -26.1, so it is a saturated vapor to a superheated vapor?

the specific volume is .14m^3

Pressure is constant? Using a T-V graph?

I dont understand how to go about this problem any help would be great!
