Ice cubes at 0^(@)C each of mass 200 g are dropped one after the other into 2 kg water at 30^(@)C in such a awayy that after the first one melts completely, the second one is dropped. If the heat energy required to melt 1 g of ice is 80 cal, determine the maximum number of ice ice cubes that can be dropped into the water such that no ice is left in the water without melting.

Ice cubes at 0^(@)C each of mass 200 g are dropped one after the other

1.	Ice cubes at 0^(@)C each of mass 200 g are dropped one after the other into 2 kg water at 30^(@)C in such a awayy that after the first one melts completely, the second one is dropped. If the heat energy required to melt 1 g of ice is 80 cal, determine the maximum number of ice ice cubes that can be dropped into the water such that no ice is left in the water without melting.
Answer» SOLUTION :HEAT lost by water=head GAINED by ice `ms_(w)(t_(2)-t_(1))=nml` `(2xx103)xx1xx(30-00)=nxx200xx80` `impliesn=3.75` ice cubes.
