Chapter 7, Problem 7.52AP

a.

Summary Introduction

To determine:

If anything will happen to the size of the balloon when we are diving in the ocean at a depth of $\text{40}\text{m}$ and take balloon filled with helium (assume temperature is same).

Concept introduction:

Boyle’s law states that “the volume of a fixed amount of gas at constant temperature is inversely proportional to the pressure”.

The volume and pressure at constant temperature is calculated by the formula,

${\text{P}}_{\text{i}}{\text{V}}_{\text{i}}={\text{P}}_{\text{f}}{\text{V}}_{\text{f}}$

b.

Summary Introduction

To determine:

If anything will happen to the size of the balloon when it slips out of the hand and floats upward before diving(assume temperature is same).

Concept introduction:

Boyle’s law states that “the volume of a fixed amount of gas at constant temperature is inversely proportional to the pressure”.

The volume and pressure at constant temperature is calculated by the formula,

${\text{P}}_{\text{i}}{\text{V}}_{\text{i}}={\text{P}}_{\text{f}}{\text{V}}_{\text{f}}$

c.

Summary Introduction

To determine:

The original volume of balloon if the assumed pressure at the surface of water is $\text{14}\text{.7}\text{psi}$.

Concept introduction:

Boyle’s law states that “the volume of a fixed amount of gas at constant temperature is inversely proportional to the pressure”.

The volume and pressure at constant temperature is calculated by the formula,

${\text{P}}_{\text{i}}{\text{V}}_{\text{i}}={\text{P}}_{\text{f}}{\text{V}}_{\text{f}}$
