Why do u not put negative on gradient?

[@SkeleFang]

Yes she missed it

[@Tsuuyoka]

For the last, part(e), is it acceptable to write use smaller volume ?? Pls reply 😊

[@CamScience]

@@Tsuuyoka i prefer concentration as decreasing volume increases %error

[@Tsuuyoka]

@@CamScience ohh I see

[@Tsuuyoka]

For qs 2(b)(ii), isn't it we have to find the temperature change every fixed intervals so can calculate mean? Can we actually use initial temperature and final temperature together and divide by 2 to obtain a mean?

[@CamScience]

@@Tsuuyoka i feel initial and final temperature does not exactly explain the time of temperature measurement. We need to specify

[@devluharuwalla1943]

gradient is calculated wrong?

[@CamScience]

@@devluharuwalla1943 no its correct

[@alviahasan6]

But I have 2580 is it correct?

[@noku06]

@@alviahasan6 Isn't the gradient different for us all since our graphs aren't identical? (My gradient is 2520)

[@delademandrewdunyoh2706]

It is correct, the mark scheme awards the mark for the gradient based on the coordinates you picked.
