    in AS practicals when do we use water bath, environmental chamber and incubator?????
    the markscheme keeps rejecting different answers each time

    environmental chamber is used when the humidity is the factor we are trying to control.
    water bath or incubator is used when temperature is the factor we are trying to control.
    so make sure you know the relevant factors to be controlled for each experiment.
    make sure you read some notes and memorize factors to be controlled for each one of them
