about Mellow-W (Note! Only one answer is required, although more than one answer may apply).
a) A temperature beyond which Mellow-W gas cannot be liquified:
b) A temperature which describes Mellow-W's melting point at standard pressure:
c) What is the temperature and pressure of the Critical Point?
d) What is the temperature and pressure of the Triple Point?__:
e) The name of the point where all three phases are in dynamic equilibrium:
f) Which best describes the phase transitions that occur when Mellow-W at 10 atm is heated from -75° C to 330° C? (Circle one):
i) solid->liquid ->gas ii) solid-gas iii) liquid->gas iv) solid -> liquid
g) Which phase best describes Mellow-W @ 1atm and 25 degrees?: i) solid ii) liquid
111) gas
h) Choose any set of conditions of temperature & pressure where Mellow-W will only be in the solid phase:
