what was independent and dependent variables and why they had one mark only

 

[Pals_1010]

what do you guys think the GT would be?

GT is usually around 18 to 20 I think

 

[Pals_1010]

what was independent and dependent variables and why they had one mark only

independent variable: mass of ammonium nitrate

dependent variable : volume of N2O

other control : temperature

I hope its like 15.. XD

 

[Pals_1010]

I hope its like 15.. XD

*fingers crossed*

 

[Sannikutti]

What about the temprature one? 110 it will increase but the ratio is same rite

 

[Sannikutti]

I think the graph should be a curve because they asked initial gradient not gradient so ya

 

[Pals_1010]

It is a straight line initially, then it becomes curved.

the first part had 3 marks then 1mark for variables and 3 for apparatus4 for experiment and 2 for hazard and 2 for table total 15
question2 was 2 for table 1 for graph 4 for big graph 2 for anamolous 2 for gradient 2 for it obeys or not and reson 2 for gradient whywe calculate and 1 for signeficance and 1 for approperiod which is why itsnot so 15 which is 30 total ryt?

Guys did question (2) stated that plot the graph of 1/V against Pressure .. ?? Actually i was running out of time so didn't read the 2nd question properly.. so can any1 pls tell me whether i'll get marks for plotting pressure against 1/V ??

 

[Pals_1010]

Actually yes. it was (1/V) against P.... You ll probably only lose marks for the plotting of graph though. Then e.c.f for the following parts (gradient etc)

What do think how many marks will i lose ??

 

[Pals_1010]

Umm... the plotting graph question was around 4 marks according to the post above. 4 marks maybe

GT - I guess would be like 17 - 18 .
questions were really tricky

independent variable: mass of ammonium nitrate

dependent variable : volume of N2O

other control : temperature

alhamduliah i was right

 

[candid24hours]

How were you supposed to use the ice bath?? Can anyone please describe the set up?

i was not havig any idea about ice so i used condensor
