What is the pressure of the gas inside the bulb (atm) if the outside pressure is 0.92 atm? (a) 1.1 atm (b) 2.6 atm (c) 0.22 atm (d) 0.70 atm

Key Concepts

Gas Laws

Gas laws describe the behavior of gases in relation to pressure, volume, and temperature. The most relevant laws for this question are Boyle's Law, which states that pressure and volume are inversely related at constant temperature, and Dalton's Law of Partial Pressures, which states that the total pressure exerted by a mixture of gases is the sum of the partial pressures of each gas.

Atmospheric Pressure

Atmospheric pressure is the pressure exerted by the weight of the atmosphere above a given point. It is commonly measured in atmospheres (atm), where standard atmospheric pressure is defined as 1 atm. Understanding the concept of atmospheric pressure is crucial for comparing the internal pressure of the gas in the bulb to the external pressure.

Pressure Equilibrium

Pressure equilibrium occurs when the pressure inside a closed system, such as a gas bulb, balances with the external pressure. If the internal pressure exceeds the external pressure, the gas will expand; if it is lower, the gas will compress. This concept is essential for determining the pressure of the gas inside the bulb in relation to the given external pressure.
