Answer:
The pressure inside the syringe will become approximately 2 atmospheres
Explanation:
The question is about the relationship between pressure and volume, hence Boyle's law which states hat the volume of a given mass of gas is inversely proportional to its pressure, provided that the temperature remain constant.
That is P₁V₁ = P₂V₂
Where:
P₁ = Initial pressure = 1 atm
V₁ = Initial volume = 30 ml
P₂ = Final pressure = Required
V₂ = Final volume = 19 ml
Plugging in the values, we have
1 atm × 30 ml= 19 ml ×P₂
∴ P₂ = 30 (atm·ml)/19 ml = 1.579 atm ≈2 atm rounded to the nearest whole number.
