Best ResponseYou've already chosen the best response.0Then acc to you 150 should be the answer but my teacher told me 423 and i dont know how??

Best ResponseYou've already chosen the best response.0No....unit is not given so we have to give the answer on the same standard as in the question

Best ResponseYou've already chosen the best response.0Bro i know all that..but i am just saying that how you knew that 75 degrees in the question is in celsius scale not in kelvin...it can possibly be given in kelvin becoz we havent mentioned any unit in the answer also....... just ''degrees'' not any unit...so it means that we does'nt have to convert 75...

Best ResponseYou've already chosen the best response.0So by keeping 75 how we can get to the answer..??

Best ResponseYou've already chosen the best response.0to get you to the bottom of this, set T to zero in the ideal gas law see what you get

Best ResponseYou've already chosen the best response.0Bro we have to find T2 and by putting T zero all the equation would be zero....i think the above question is a simple condition of Charles law nothing more thn that and the answer should be 150 according to me but my teacher told me thats not the answer answer is 423 and i was just wandering how the hell this can be the answer and i just supposed if there is a trick behind it so just want you to find that out...please...

Best ResponseYou've already chosen the best response.0really sorry mate, finally gave this the attention it deserves and i totally dig what you say here we have: dw:1442512924916:dw so #1 \[\frac{1 \times 1}{75K} = \frac{1 \times 2}{X}\] \[X = 2(75) = 150K \] or #2 \[\frac{1 \times 1}{75^oC+273} = \frac{1 \times 2}{X+273}\] \[X+273 = 2(75+273)\] \[X = 423K = 150^oC\] good spot!
