Under ordinary conditions, a substance will sublime rather than melt if
a. its triple point occurs at a pressure above atmospheric pressure
b. its critical temperature is above its normal boiling point
c. its critical point occurs at a pressure above atmospheric pressure
d. its triple point occurs at a pressure below atmospheric pressure
e. its critical point occurs at a temperature above room temperature

C

Explanation:

Under ordinary conditions, a substance will sublime rather than melt if its critical point occurs at a pressure above atmospheric pressure.

At conditions below the triple point that is under ordinary conditions , it is a solid to gas transition, vaporization only occurs above the triple point.

Hence the most correct answer is Option C.

personal, she chose to do it.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
