Question
At a given pressure, a substance in the saturated vapour phase will be at a ____ temperature than a superheated vapour.Group of answer choicesthe samehigherlower
Solution
The correct answer is "lower".
Here's why:
-
A substance in the saturated vapour phase is at its boiling point for a given pressure. This is the highest temperature it can reach under this pressure while still having some liquid present.
-
When a substance is superheated, it means it's heated beyond its boiling point at a given pressure. This means all the liquid has turned into gas, and the temperature can continue to rise.
-
Therefore, at a given pressure, a substance in the saturated vapour phase will be at a lower temperature than a superheated vapour.
