for line graphs, should we always draw/connect points with a straight line unless it specifies in the question to draw line of best fit? or should we kind of examine the question and points/results to choose whether a straight line or line of best fit is suitable for the graph? i have an exam tomorrow so please reply quickly thank you
no significant figures means the answer u get should be three numbers for example the number you wrote is 4 significant figures you get? so the answer was indeed supposed to be 0.29 or 0.30
@@callmeKATawanda like there are dots scatter in the graph and tend to go up or down. best fit line is the line you should draw here to represent the trend of the dots(in the middle of them)
Brother...i cannot thank you enough for how much you help...may you grow in life successfully
will this paper come in exam?
@@user-ob6yc3em9zmaybe somewhat similar because chemistry paper 4 was similar of feb/march of 2024
thank you so much.. youre a very enthusiatic teacher
You're very welcome!
Actually heading to the hall😢
very helpful, even for O levels🤗🤗🤗
for drawing the tables is it a must to include the independent varibles in the left and dependent on the right ??
Yes

my teachers told us its not that important. as well as the line doesnt devise too much. I draw half straight half curve
Hi! For part 1 (b) (i) can we say using a thermostatically controlled water bath, because it helps us control one of the variable?
idts...cause it doesnt say in the ms. tho it does sound like a viable answer
I believe we can
18:09 they asked for 3 significant figures so the answer in your case should be 0.294

@@CitySolesAccessoriesim pretty sure the 0 in the front doesn’t count as a significant figure right
@@arshiatanisha it very much does
@@CitySolesAccessoriesit very much doesn't
@@zxyify2 yeah it very much doesn't, any preceding zeros don't count as a significant figure. hope citysoles gets it right before the exam
helloooo when plotting graphs should i ALWAYS use a ruler?
no as some questions clearly says "best fit curve" and in those questions if you used a ruler you will loose marks
@dinoyt1916 please explain again on "best fit curve"

for the last question is it ok if i wirte subheadings for the method,variables i would control and safety and etc
Do you write the last question in point format?
I don't really think it matters as long as there is enough space
For the table 1:34, i thought the student recorded the result as >600 ?
For the last question is it ok if write subheading for the varibles,method safety and etc
