Yeah. I ticked the first and second one. The first one is obviously right but my friends are saying that the second one was wrong? Are you really confirmed about it, eh? :S

 

[jafar]

to use thicker oil is rong.....
first 2 boxes were to be checked

 

[Zishi]

@Jafar: Have you confirmed it with teachers, dude?

 

[miracle]

two students and the other was to take the temp. measurement quickly after heatin

 

[Mueez]

yes u r right

 

[Balaj Hassan]

I also ticked 2nd and last box i.e two students and take reading quickly thing.
Are u guys sure this is right???
From whom have u guys confirmed it???

 

[jafar]

i think there were more than 2 answers of this questions cuz

usin sensitve thermometer is right cuz it gives more accurate reading,
2 peoplle take da readin so ther will be less error
using thicker oil cuz den its temp will change mor slowly will change more slowly
taking the readin quickly as oil changes temperature fastly so there will be less error...

all of these seemcorrect 2 me :S

 

[miracle]

i m not really sure whether 2 or more ans can b correct frm the options..... :shock:

 

[Deeva]

I ticked the last two. The one about pouring it quickly after heating and taking a larger range of readings.....
