The isothermal compressibility of lead is 2.21E-6 atm-1. Express this value in Pa-1. A cube of lead of side 10 cm at 25C is to be inserted in the keel of an underwater exploration TV camera, and its designer needs to know the stresses in the equipment. Calculate the change of volume of the cube at a depth of 1.000 km (disregarding the effects of temperature). Take the mean density of sea water as 1.03 g/cm3. Given that the expansion coefficient of lead is 8.61E-5 K-1 and that the temperature where the camera operates is -5C, calculate the volume of the block taking the temperature into account too.
