The drinking bird works by evaporation of ether inside its body and evaporation of water outside its head. The liquid ether in its body evaporates at room temperature. As it vaporizes it creates an increased pressure inside the body, which pushes liquid ether up the tube to the head.
The first law of thermodynamics, also known as law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.
the solubility of oxygen decreases as temperature increases.
so basically warmer water has less dissolved oxygen.
i used to be in biosite my sophomore year and we would answer these questions all the time.
