An air bubble has a radius of 0.50 cm at the bottom of a water tank where the temperature is 280 K and the pressure is 280 kPa. When the bubble rises to the surface, the temperature changes to 300 K and pressure to 300 K and pressure to 100 kPa. Calculate the radius of the bubble at the surface

Explanation

To solve the problem of finding the radius of an air bubble at the surface of a water tank, we can follow these steps:

### Step 1: Understand the Problem
We are given the initial conditions of the bubble at the bottom of the tank (temperature, pressure, and radius) and the final conditions at the surface (temperature and pressure). We need to find the new radius of the bubble at the surface.

### Step 2: Write Down the Known Values
- Initial radius (r1) = 0.50 cm
- Initial temperature (T1) = 280 K
