Physics paper 31 , (a death call)

[nabbbb]

The paper was easy.

 

[syed1995]

How would you compare the 3 papers' difficulty?

 

[DOS]

it was

 

[IGCSE O/L student]

also what was the question abt the change of state ?

i wrote for the first part water freezes to form ice
and the second part, i wrote there's no effect on temperature

I wrote decrease in temp because from some temp to 0 degrees ...wat u thnk???

 

[IGCSE O/L student]

no it was 6 V

no, i'm 100% sure it is 2.4V

 

[IGCSE O/L student]

ummm. idk if u'll get marks, but they asked to give an example where the state changes.
when a state changes, the temperature of the substance does not change

beta particles were outwards

out of the page

yes u r ryt.....WISH U A*

 

[IGCSE O/L student]

yes u r ryt.....WISH U A*

jazakallahu khair!
Aameen!
you too!

out of the page

same thing lol

 

[IGCSE O/L student]

same thing lol

yes, hahahahahhah...

 

[bluefa1con]

no, i'm 100% sure it is 2.4V

yeah just realized that *facepalm* 3*0.8=2.4
but i think we will only be losing 1 mark since the whole question was solved correctly based on that error so ecf marks

yes, that's right.

can the example of change of state be "evaporation"?

 

[IGCSE O/L student]

can the example of change of state be "evaporation"?

I don't think so, areeba. because heat is not removed. you have to supply heat!

 

[bluefa1con]

can the example of change of state be "evaporation"?

no because for evaporation energy is taken in not given out

i wrote 0.378 ohms for the resistance R , i don't know my steps are right or not through out the question !! but if wrong can i still get a high mark in the question!

If you wrote the formula, then there is a possibility.

 

[kim anika]

so wat did u get as de max. height of jet??

its 1.something.........i think its 1.15
