Answer:
3.8 cm
Explanation:
Given data
- Initial pressure (P₁): 3.2 atm
- Initial volume (V₁): 65 cm³
Volume of a sphere: V = 4/3 × π × r³ = 4/3 × π × (2.5 cm)³ = 65 cm³
- Initial temperature (T₁): 5.4°C + 273.15 = 278.6 K
- Final pressure (P₂): 1.0 atm
- Final volume (V₂): ?
- Final temperature (T₂): 25.0°C + 273.15 = 298.2 K
We can find the final volume using the combined gas law.
The final radius of the bubble is:
V = 4/3 × π × r³
223 cm³ = 4/3 × π × r³
r = 3.8 cm
