    What did you put for the final question? The one asking for what improvements Zac should have made? And what did you get for the temperature change and the volume?

    I said the heat is lost to the surroundings and an improvement would be to to put it in a beaker with cotton wool
    For the temperature change I got around 6. Something and for the volume I did two lines of best fit and where they intercepted was the volume and mine was around 23 but think mine was low cause everyone else got there's to be about 24
    I don't these are right but just saying what I did

    I think the volume will be within a range because everyone can have different lines of best fit

    In section A, what did people get for calculating the moles from the half life? I got 0.011, or something like that? and Radon for the question before that...
