The balloon is filled with 0.5L of air at sea level and submerged to a depth. Since, there is no change in the Temperature, the process is Isothermal. It is a process in which the temperature T of the given system does not change and remains constant. Hence, ΔT=0
Any system in which the temperature is kept constant is stated as an Isothermal Process. Since, in the given question, Temperature is not changing, hence we can consider it to be an Isothermal Process.
Given:
Pressure at sea level, P₁= 1 atm
Volume at sea level, V₁= 0.5L
Pressure at depth, P₂= 3.25 atm
Volume at depth, V₂= ?
Since, the process is Isothermal, hence,
∴ P₁V₁ = P₂V₂
⇒ 1 × 0.5 = 3.25 × V₂
⇒ V₂ = 0.5/3.25
⇒ V₂ = 0.154L
So, the Volume of balloon at the depth is 0.154L.
