FL #1 C/P Question 13

Postby heatfan » Sun Jun 10, 2018 1:48 am

Hello,
I was looking at one of the wrong answer choices trying to understand the rationale in the explanation. It states that "Water condenses from vapor into liquid at low temperatures, not high temperatures. Here, we are heating the distillation apparatus, so water would not be expected to condense." Why does water condense at lower temperatures, is this because of the hydrogen bonding? Also, is this true for other element and compounds? Thanks.

Water condenses into liquid at low temperatures because all gases condense into liquid at lower temperatures. This is due to a decrease in the internal energy of the gas resulting in its vapor pressure being less than atmospheric pressure.
