Answer:
1.9 atm
Explanation:
Using Boyle's law :
Pressure is inversely proportional to volume Given that temperature and mass remains constant.
Mathematically ;
P1V1 = P2V2
P1 = 0.95 ; V1 = 1.5L; P2 = ? ; V2 = 1.5 - (1/2*1.5) = 0.75 L
P1V1 = P2V2
0.95 * 1.5 = P2 * 0.75
1.425 = 0.75P2
P2 = 1.425 / 0.75
P2 = 1.9
P2 = 1.9 atm
