The room in which the cylinder is placed catches fire. Predict whether the cylinder will blow up before it melts or not.....

2) The density of a gas at 27 degrees celcius and 760mm pressure was found to be 3g/l. Find out the temperature at which the density will become 2.4g/l, keeping pressure constant


Please answer


Thanks :)

this is physics right..........u guys are already so far ahead? i dont know how to answer this q cuz i aint studied this.........sory :-[

astarmathsandphysics:
I modified my post too.

nid404:
thanks sir


but shouldn't the second  be  1/T1d1=1/T2d2


considering vapour density :-\
