the pressure exerted by 12 grams of an ideal gas at temperature t degree celsius in a vessel of volume v ltr is 1 atm when the temperature is increased by 10 degree celsius at the same volume the pressure increases by 10 %. Calculate the temperature t and volume v (molecular weight of the gas eqal to 120)In the solution why you have taken t in k in equation 1 and 2 where as in question t?C

By PV=nRT ( here T is used in Kelvin )

First equation becomes 1*v=12/120*R*T
Second equation 1.01*v=12/120*R* (T+10)
Solving 1.01*T=T+10
T=1000K
Sp T=1000-273 K

i have taken in kelvi because in ideql gas equation temperature alwYas ha sto be in its SI unit

so here even it isgiven in celsius it has to convereted in kelvin

thanks and regard
