1. The volume of the air is 2500 cm³
2. The pressure in the tyre is 2.27 atm
<h3>Boyle's law equation</h3>
P₁V₁ = P₂V₂
Where
- P₁ is the initial pressure
- V₁ is the initial volume
- V₂ is the new volume
- P₂ is the new pressure
<h3>1. How to determine the new volume </h3>
- Initial pressure (P₁) = 2.5 atm
- Initial volume (V₁) = 1000 cm³
- New pressure (P₂) = 1 atm
- New volume (V₂) = ?
P₁V₁ = P₂V₂
2.5 × 1000 = 1 × V₂
V₂ = 2500 cm³
Thus, the volume of the air is 2500 cm³
<h3>2. How to determine the new pressure</h3>
- Initial pressure (P₁) = 2.5 atm
- Initial volume (V₁) = 1000 cm³
- New volume (V₂) = 1000 + 100 = 1100 cm³
- New pressure (P₂) = ?
P₁V₁ = P₂V₂
2.5 × 1000 = P₂ × 1100
Divide both sides by 1100
P₂ = (2.5 × 1000) / 1100
P₂ = 2.27 atm
Thus, the pressure in the tyre is 2.27 atm
