Question

At 35°c and 700mn of Hg pressure ,a gas occupies 500 ml volume.what will be its pressure when the temperature is 15°c and the volume of the gas is 450ml

Answer 1

Explanation:

I don't know the answer but I can give you clue.

calculate the second pressure by the formula:

P1V1/T1= P2V2/ T2

I'm sry but.. this is too lengthy calculation...

Answer 2

Answer:

727mmhg

Explanation:

T1=35+273=308

P1=700mmhg

V1,=500ml, V2=450ml

T2=15+273=288

then the equation will be

P1V1/T1=P2V2/T2

700*500*/308=P2*450/288

P2=700*500*288/450*308

P2=727mmhg

hence the proof
