What is the fractional change in the volume of the hagfish when it is brought to the surface?
Various species of hagfish, or slime eels, live on the ocean floor, where they burrow inside other fish, eating them from the inside out and secreting copious amounts of slime. Their skins are widely used to make eelskin wallets and accessories. Suppose a hagfish is caught in a trap at a depth of 200 m below the ocean surface, where the water temperature is 10°C, then brought to the surface where the temperature is 15°C. If the isothermal compressibility and volume expansivity are assumed constant and equal to the values for water,
the specific volume, isothermal compressibility, and volume expansivity of several liquids at 20°C and 1 bar25, where ? and ? may be assumed constant.
