Chemistry

You may have heard that ice skaters actually skate on a thinlayer of water rather than solid ice (which reduces friction on theblade and allows them to skate faster). Letâ€™s work through acalculation to determine if this statement is reasonable. Estimatethe pressure exerted by a 200-lb hockey player, standing on twoblades that are 0.1 mm ï‚´ 20 cm. Calculate the melting point of icebelow the player, assuming that the density of ice under theseconditions is approximately 0.915 g cm^â€“3 and that ofliquid water is 0.998 g cm^â€“3. Assuming a typicaltemperature of ice in a skating rink is 27 Â°F, does a hockey playerskate on ice or water?
