Chapter 6: Problem 11

Explain why aluminum cans are good storage containers for soft drinks. Styrofoam cups can be used to keep coffee hot and cola cold. Why is this?

Short Answer

Expert verified
Aluminum cans are good storage containers for soft drinks due to their lightweight, durability, corrosion-resistant nature, and ability to be hermetically sealed, preserving freshness and flavor. Styrofoam cups can keep coffee hot and cola cold because of their excellent insulating properties, low thermal conductivity, and cost-effectiveness. These characteristics make them suitable for maintaining the desired temperature of both hot and cold beverages.

Step by step solution

01

Properties of Aluminum Cans

Aluminum cans are lightweight, durable, and resistant to corrosion. They are made from a thin layer of aluminum that can withstand the pressure exerted by carbonated soft drinks, preventing leaks and preserving the drink's freshness.
02

Aluminum Can Sealing

An important aspect of using aluminum cans for storing soft drinks is their ability to be hermetically sealed. This air-tight seal prevents air and bacteria from entering the can, protecting the soft drink from spoilage and preserving its flavor.
03

Recycling and Manufacturing

Aluminum cans are recyclable and more environmentally friendly than alternatives such as plastic bottles. This material can be melted down and recycled multiple times, requiring less energy in the process. Additionally, producing aluminum cans is more energy-efficient than producing glass bottles.
04

Properties of Styrofoam Cups

Styrofoam, or expanded polystyrene foam, is an excellent insulator with low thermal conductivity. It is lightweight, cost-effective, and can be easily molded into different shapes, making it an ideal material for cups.
05

Insulation of Styrofoam Cups

Styrofoam cups are excellent insulators due to the trapped air within their structure. The air pockets in the foam slow down heat transfer between the liquid and the environment, making it possible to keep hot drinks hot and cold drinks cold. In conclusion, aluminum cans make good storage containers for soft drinks because of their lightweight, durable, and corrosion-resistant nature. They can be hermetically sealed to keep the drink fresh and are more environmentally friendly than other alternatives. Styrofoam cups can be used to keep coffee hot and cola cold because of their insulating properties, low thermal conductivity, and cost-effectiveness.

The bomb calorimeter in Exercise 112 is filled with 987 \(\mathrm{g}\) water. The initial temperature of the calorimeter contents is $23.32^{\circ} \mathrm{C} .\( A \)1.056-\mathrm{g}\( sample of benzoic acid \)\left(\Delta E_{\mathrm{comb}}=\right.\( \)-26.42 \mathrm{kJ} / \mathrm{g}$ ) is combusted in the calorimeter. What is the final temperature of the calorimeter contents?

The heat capacity of a bomb calorimeter was determined by burning 6.79 g methane (energy of combustion \(=-802 \mathrm{kJ} /\) $\mathrm{mol} \mathrm{CH}_{4}\( in the bomb. The temperature changed by \)10.8^{\circ} \mathrm{C} .$ a. What is the heat capacity of the bomb? b. A 12.6 -g sample of acetylene, \(\mathrm{C}_{2} \mathrm{H}_{2},\) produced a temperature increase of \(16.9^{\circ} \mathrm{C}\) in the same calorimeter. What is the energy of combustion of acetylene (in $\mathrm{kJ} / \mathrm{mol} )$ ?

A piston performs work of \(210 . \mathrm{L} \cdot\) atm on the surroundings, while the cylinder in which it is placed expands from \(10 . \mathrm{L}\) to 25 \(\mathrm{L}\) . At the same time, 45 \(\mathrm{J}\) of heat is transferred from the surroundings to the system. Against what pressure was the piston working?

The enthalpy change for a reaction is a state function and it is an extensive property. Explain.

Consider a balloon filled with helium at the following conditions. $$ \begin{array}{l}{313 \mathrm{g} \mathrm{He}} \\ {1.00 \mathrm{atm}} \\ {1910 . \mathrm{L}} \\ {\text { Molar Heat Capacity }=20.8 \mathrm{J} / \mathrm{C} \cdot \mathrm{mol}}\end{array} $$ The temperature of this balloon is decreased by \(41.6^{\circ} \mathrm{C}\) as the volume decreases to \(1643 \mathrm{L},\) with the pressure remaining constant. Determine \(q, w,\) and $\Delta E(\text { in } \mathrm{kJ} \text { ) for the compression of }$ the balloon.
