I'm having an argument with a friend. He claims that warm water (above
freezing) in deep areas of the ocean are caused by the high pressure of the
water. I said he was wrong because even though deep water is under
pressure, it doesn't COMPRESS much, intermolecular collisions don't increase
much, yada yada...
He then claimed that even though the water itself doesn't compress,
dissolved gasses in the water DO compress, heat up, and heat the surrounding
water through conduction. Since I don't know if this can happen, Im hoping
somebody here does.

Thanks!

Matt

But it takes so long to fall that the heat loss would occur in mid
depths anyway plus the heat factor would stop it falling.

But I've read fairly recently that compression does take place and that
there is an heating element to this. Again heating would cause the
heated to rise -or slow the rate of descent wouldn't it?
