 The  new volume is  1.9  ml


<u><em> calculation</em></u>

The new   volume  is  calculated using the   combined gas  equation

that is  P1V1/T1 = P2V2/T2  where

P1= 1.0 atm

V1= 21   ml

T1 = 10.0 c  into kelvin = 10 + 273 = 283 k

P2 = 15 atm

V2=? Ml

T2 = 120 c  into kelvin = 120 +273 = 393 K


make V2  the subject of the   formula by  multiplying  both side  by T2/P2

V2=T2P1v1 / P2T1

V2=[(393 k  x 1.0 atm  x 21  ml) / (15 atm x 283 K)]  = 1.9  Ml
