Water has a density of 0.997 g/cm^3 at 25 degrees c; ice has a density of 0.917 g/cm^3 at -10 degrees c. (question part a) if a soft drink bottle whose volume is 1.50l is completely filled with water and then frozen to -10 degrees c, what volume does the ice occupy? (question part b) can the ice be contained within the bottle?

During its manufacturing process, fantra fills its 20 fl oz bottles using an automated filling machine. this machine is not perfect and will not always fill each bottle with exactly 20 fl oz of soft drink. the amount of soft drink poured into each bottle follows a normal distribution with mean 20 fl oz and standard deviation 0.2 fl oz. the fantra quality testing department has just carried out a routine check on the average amount of soft drink poured into each bottle. a sample of 20 bottles were randomly selected and the amount of soft drink in each bottle was measured. the mean amount of soft drink in each bottle was calculated to be 19.87 fl oz. the fantra chief executive officer believes that such a low mean is not possible and a mistake must have been made. calculate the probability of obtaining a sample mean below 19.87 fl oz. give your answer as a decimal to 4 decimal places.

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?
