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 |
