Samira’s son is older because there are 12 months in a year and we can gather that 12+12=24 so we know that Paulina’s son is younger because he is only 18 months.
Answer:
The pressure inside the chamber is 0.132 atm
Explanation:
Step 1: Data given
The initial volume = 0.027 L
The initial pressure = 1.0 atm
The volume changes to 0.205 L
Step 2: Calculate the pressure
P1*V1 = P2*V2
⇒with P1 = the initial pressure = 1.0 atm
⇒with V1 = the initial volume = 0.027 L
⇒with P2 = the changed pressure = TO BE DETERMINED
⇒with V2 = the changed volume = 0.205 L
1.0 atm *0.027 L = P2*0.205 L
P2 = 0.027/0.205
P2 = 0.132 atm
The pressure inside the chamber is 0.132 atm
