Answer to Problem 1RQ

The two broad categories of display cases are open and closed.

Explanation of Solution

The display case is a cabinet made up of a transparent material. It is used to display objects for viewing. It can be seen in restaurants, stores, or maybe in a house.

Display cases are also used in retail stores to preserve food and other things, which are displayed to the customers for sale. The customers can select items from the section of the store and choose any of them to purchase. Some of the display cases are open which allows the customer to reach in without opening a door. The closed display cases are more energy efficient as compared to open display cases. These display cases are available in different temperature ranges such as low, medium, and high-temperature range. An open display case maintains temperature conditions. This is because the refrigerated air is heavy and it gets settled at the bottom. This is achieved by designing and maintaining air patterns, which keep the refrigerated air from leaving the case.

Conclusion:

The two broad categories of display cases are open and closed. Both of them have their own characteristics as explained earlier.
