Chapter 10, Problem 43c

Chlorine is widely used to purify municipal water supplies and to treat swimming pool waters. Suppose that the volume of a particular sample of Cl2 gas is 8.70 L at 119.3 kPa and 24 °C. (c) At what temperature will the volume be 15.00 L if the pressure is 116.8 kPa

Verified step by step guidance
1
Identify the initial and final conditions of the gas: Initial volume \( V_1 = 8.70 \text{ L} \), initial pressure \( P_1 = 119.3 \text{ kPa} \), initial temperature \( T_1 = 24^\circ \text{C} \), final volume \( V_2 = 15.00 \text{ L} \), and final pressure \( P_2 = 116.8 \text{ kPa} \).
Convert the initial temperature from Celsius to Kelvin using the formula \( T(K) = T(^\circ C) + 273.15 \).
Use the combined gas law, which is \( \frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2} \), to relate the initial and final states of the gas.
Rearrange the combined gas law to solve for the final temperature \( T_2 \): \( T_2 = \frac{P_2 V_2 T_1}{P_1 V_1} \).
Substitute the known values into the equation and solve for \( T_2 \) in Kelvin.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Ideal Gas Law

The Ideal Gas Law relates the pressure, volume, temperature, and number of moles of a gas through the equation PV = nRT. This law is fundamental in understanding gas behavior under varying conditions. In this scenario, it helps to determine how changes in temperature and pressure affect the volume of chlorine gas.

Ideal Gas Law Formula

Charles's Law

Charles's Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when pressure is held constant. This principle is crucial for solving the problem, as it allows us to predict how the volume of Cl2 gas will change with temperature adjustments while considering the pressure changes.

Pressure-Volume Relationship

The relationship between pressure and volume of a gas is described by Boyle's Law, which states that at constant temperature, the pressure of a gas is inversely proportional to its volume. Understanding this relationship is essential for analyzing how the pressure of chlorine gas changes when the volume is altered, as seen in the given problem.

A 50.0 g sample of solid CO2 (dry ice) is added at -100 °C to an evacuated (all of the gas removed) container with a volume of 5.0 L. If the container is sealed and then allowed to warm to room temperature 125 °C2 so that the entire solid CO2 is converted to a gas, what is the pressure inside the container?
