Answer :
An engine cylinder compresses an air mixture from 250. mL to 24.2 mL, then its new pressure is 7,704.54 mmHg.
What is Boyle's law?
Boyle's law of gas states that at constant temperature, volume of gas is inversely proportional to the pressure of the gas.
For this question equation becomes:
P₁V₁ = P₂V₂, where
V₁ = initial volume = 250mL
P₁ = initial pressure = 745.8 mmHg
V₂ = final volume = 24.2mL
P₂ = final pressure = ?
On putting these value on the baove equation, we get
P₂ = (745.8)(250) / (24.2) = 7,704.54 mmHg
Hence new pressure is 7,704.54 mmHg.
