I dont know about that. What beliefs?

Science does assume the world can be describesd, understood and modeled. And this is borderline contradicted by quantum physics. Other than that, science does not believe anything, even if scientists inevitably hold beliefs of their own. But a scientific theory is just a model than can explain what we can observe, sometimes with some best guesses- you're welcome to challenge them, but be ready to answer some tough follow-up questions.

Apart from what others have said, the phase change can be seen as a nifty way to realize the carnot cycle. The phase changes are isotermic, and expansion valve is a simple way to get an almost isentrpoic expansion. Just the compressor to work on.
