    Yup thank you :D Coz i came across a question where they gave us a table stating boiling points and melting points of substances and wanted us to state which substances are liquid, solid, gas etc at room temperature and im not really sure how to tell. This question usually comes up in paper 3...

    noo the point at ph 5 is wrong as it is not on the line that the other points run under so u dont join that point when you draw your line and this is a free hand drawing you just have to draw a "smooth line" meaning just including the points that will allow for your line to be smooth and as you...
