Always remember whenever resistance decreases the current has to increase okay!
If temperature increases that means the resistance decreases which means the current will increase.
Always remember as light or temperature increases resistance will decrease which means current will increase,as the decrease it will increase which means less current.
As you know for a variable resistor if we increase the resistance it will decrease the current ,and decrease resistance will increase the current.

In tritrations in paper 4...why does the marking scheme tells the colour change from acid to alkali or alkali to acid...shouldn't it be acid to neural or alkali to neutral

actually, the volume of alkali needed to neutralise an acid is the point where an acid (H+ ion) is in excess to when an alkali (OH- ion) is in excess. It is actually very difficult to exactly pour out the same number of OH- ions as there are H+ ions, so the little excess of OH- ions results in alkaline solution.

Y are u in tension about this? just make sure u know the colour change!

Assalam-o-Allaikum and Hi everyone ,
hope u all are doin great !

Well as the topic says help for chemistry :D biology :D and Physics :D is available here that means that u can ask any mind blowing question or ask any question regarding a particular topic or ask abt any questions from Past paper or any of your text books. (y) (y)

I made this topic so that people dont make many posts asking abt bio,physics or chemistry individually but they can post their reply here where it can be answered with ease and the members wont have to go searching for topics to help! :D !

So what are u waiting for now write ur questions here !
THANKS and Bye or Allah Hafiz ! :wink: :good:
