There doesn't have to be a single answer, depending on specific situations, but for water in convection, it will tend to be colder lower and warmer higher up. The atmosphere has the opposite because air expands as the pressure drops, resulting in cooling.Cheesycheese213 said:Hi, so someone probably has already asked this, but does temperature increase or decrease with depth in a fluid? I thought it would decrease since it has more pressure but it is probably wrong, or doesn't make sense. I was confused because the ocean gets colder the deeper you go, but then does the same thing happen with increasing altitude? Sorry if this is a dumb question, but I got really confused. Thanks!
Ohhhh okay, so it depends on the fluid? Thank you so much a,russ_watters said:There doesn't have to be a single answer, depending on specific situations, but for water in convection, it will tend to be colder lower and warmer higher up.

You're welcome, but it isn't just the fluid, it also can depend on specifics of the situation. For example, in most buildings, it is warmer higher up because of stratification; the same reason why liquids are sometimes warmer higher up. That's because for relatively small altitude differences, there isn't enough density change to allow for cooling due to expansion.Cheesycheese213 said:Ohhhh okay, so it depends on the fluid?
