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

Initial pressure (P₁): 3.2 atmInitial temperature (T₁): 7 °C = 305 KInitial radius (r₁): 2.5 cmFinal pressure (P₂): 1 atmFinal temperature (T₂): 25 °C = 298 KFinal volume (V₂): ?

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.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
