    I need help understanding some concepts

    Say you carry out a experiment for the combustion of alcohol using 300 cm3 of water and 4.50g of alcohol in order work out q=mc∆t. Say this is your standard experiment

    And you do variations to this experiment

    using smaller volume of water
    Why is it that mc∆t is the same, if you use asmaller amount of water?

    Using larger mass of alcohol
    Why is mc∆t the same if you burn a larger mass of alcohol?

    Burning alcohol for longer period of time
    Why is mc∆t the same when you burn the alcohol for a longer period of time?
