Answer»

P2 / P1 =  T2/ T1           10^6  / 0.25 * 10^6  =  T2 / 300 K         => T2 = 1200 K       It will  blow up at  1200 K============3.       P1 = 5 atm      T1 = 303 K          V1          n1      m1               P1  V1 =  n1  R T1     T2  = 293 K,       n1,   m1 same     V2  = 160% V1 = 1.6 V1           =>    P2 =  P1 /1.6     n3 =  n1 * 120%  = 1.2 n1            V3 = V2 = 1.6 V1     T3 = ?        P3 =  P1       P3 V3 / [P1 V1 ] =  n3 R T3 / [ n1 R T1 ]       1.6 = 1.2 * T3 / 303         T3 =  1.6 / 1.2 *    303 K========================4.I think there is a misprint in the number :  10 deg C  increase in temperature or  10% increase in pressure....    Increase of 10 deg. C  cannot increase pressure by 10%.m = 12 gm          T1 = 273+t deg K          V1 = v litre        P1 = 1 atmM = 120        => n = 0.1  number of molesif the increase of temperature is:  100 deg C   T2 = 373+t  deg K            V2 = v litre        P2 = 1.10  atm       P2/P1 = T2 / T1      =>     1.10 (273 + t) = 373 + t               =>    t = 10 *  72.7  =  727 deg Cif the increase of pressure is 1 % only and increase of temperature is 10 degC,             P2/P1 = 1.01 = 283+t  / (273+t)                   t = 727 deg  C=================================then CALCULATE V as:          v  = n *  R (273+t)  / P1          as all quantities are known
