AI Thread Summary
The critical temperature is the highest temperature at which a substance can exist as a liquid, regardless of pressure. Water has a higher critical temperature than dioxygen due to the presence of hydrogen bonding, which stabilizes its liquid state. The original poster expressed confusion about the concept but recognized that hydrogen bonding plays a crucial role in this comparison. Ultimately, understanding critical temperature is essential for comparing the states of different substances under varying conditions. The discussion highlights the importance of grasping fundamental concepts in thermodynamics.

Homework Statement



Compare the critical temperature of dioxygen and water.


The Attempt at a Solution



I don't know what critical temperature means here. If someone could tell me what that means, I am pretty sure I could answer the question.

Ouch. The critical temperature of water will be higher than that of dioxygen cause of hydrogen bonding. Right? Kinda dumb... don't know what I was thinking of...physics probably...
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
