People sit in rubber boats, boats dipped in water, a certain depth, to the night, the temperature has decreased, but the atmospheric pressure is constant, ask the boat immersed in water, how will the depth change?
The submarine submerged in the volume of boiling water, no matter how deep submergence has always been the same, so the submarine suffered
The relationship between pressure and depth. When you dive into the water, you feel bored because of the pressure of the water
Because the night temperature is low, the ship volume decreases, V decreases, but V is constant, V is equal to the displacement of the gravity drainage plus aboard gravity accordingly. Therefore, to maintain the original V row, hull certainly can V reduce the decline (here understood as hull thinning, so to maintain the original the row V volume, depth to increase).
