A start-up company is marketing steel “ice cubes” to be used in place of ordinary ice cubes. How much would a liter of water, initially at 20 ^◦C, be cooled by the addition of 10 cubes of steel, each 2.5 cm on a side, initially at −10 ^◦C? Compare your result with the effect of 10 ordinary ice cubes of the same volume the same initial temperature. Would you invest in this start-up? Take the density of steel to be 8.0 gm/cm³ and assume the heat capacities to be constants, independent of temperature.
