An air bubble at the bottom of lake with temperature 7 0C and pressure of 3.2 atm has a radius of 2.5 cm. It rises to the surface where the temperature is 25 oC and atmospheric pressure is 1 atm. What is the volume of the bubble at the surface? Assume perfect gases. V=(4/3)πr3.

Explanation:

Step 1: Given data

Step 2: Calculate the initial volume

We will use the following expression.

V = 4/3 × π × r³

V = 4/3 × π × (2.5 cm)³

V = 65 cm³

Step 3: Calculate the final volume

Assuming ideal behavior, we can calculate the final volume of the bubble using the combined gas law.

c- cold periods in earth's history during which glaciers covered much of the surface.
