Ice cream and freezing point depression

  1. Jun 19, 2006 #1
    When you make ice cream using a couple of zip loc bags and a salt/ice mixture do the room and surroundings have any effect? Can you be in a warm room and still make the ice cream? Thanks.

    Well the room and the surroundings always have some effect on the results of an experiment, but with the ziploc bags you are trying to achieve a closed system, in which no matter or heat can be transfered to the surroundings. The influence of the surroundings, in this case, is negligible. So, yes you can still make ice cream in a warm room, but it might be a little difficult in a sauna :smile: .
