In a thermal expansion of water lab, a glass bottle of water is cooled to 0 degrees and the water level is observed as the temperature rises. there is a decrease in water level from 0 degrees to 4 degrees. then, at about 15 degrees when the bottle is placed in a warm bath (30 degrees), why is there another small and almost instant decrease in the water level when placed in the warm bath before it starts to rise again?
