Answer:
Explanation:
New pressure will be - 1.9 atm.
Boyle's law states that "pressure of a given quantity of gas is inversely proportional to its volume at a constant temperature."
The equation representing Boyle's law is P1V1 = P2V2
P1 and P2 represent initial and final pressure and V1 and V2 represent the initial and final volume.
Initial pressure given in the question is 0.95 atm.
The initial volume is 1.5 l and the final volume is 1/2 of its value, thus 0.75l.
Keeping values in the formula,
0.95*1.5 = P2*0.75
P2 = 1.9 atm
Thus, new pressure will be 1.9 atm.
