II. Exemplary Essay: Describing Household Items
Every household requires a plethora of items for daily living, each serving its unique purpose and benefit. A water pitcher stands as an indispensable item that every household should possess for daily use.
The water pitcher was invented and introduced in 1892 by the Scottish physicist Sir James Dewar. Originating from the cumbersome calorimeter invented by Newton, Dewar ingeniously developed it into a thermos flask. Upon its discovery by two German glassblowers for its heat-retaining properties, it was transformed into a commercially available product distributed worldwide.
The pitcher typically has a cylindrical shape, ranging from 45 to 50 centimeters in length. It consists of two main parts: the pitcher body and the pitcher shell. The shell is commonly made of metal or plastic and is adorned with various patterns and colors, allowing users to choose a preferred and suitable design. The shell includes a lid, which prevents water vapor from escaping, minimizes heat transfer, and prevents spills. If the shell is made of metal, the lid is wooden; if the shell is plastic, the lid matches the material. The lid also doubles as a drinking cup when necessary or serves as a water container. The pitcher body is equipped with a handle for easy gripping and transportation, particularly useful for longer journeys. Additionally, the pitcher is designed with a base to maintain balance and stability for the inner container. The inner container, also cylindrical, is made of silver-coated glass, a material that aids in reflecting heat rays to retain water temperature. The vacuum layer between the glass layers serves to insulate the water.
The primary function of a water flask is to retain heat. Typically, when pouring boiling water at 100 degrees Celsius, within 6 - 7 hours, the flask can maintain the temperature of the water from 100 degrees C to around 70 degrees. Hot water ensures convenience for brewing tea, coffee, or necessary for patients in hospitals. Particularly, the water flask is also an essential item for instant noodle enthusiasts. During winter, every household usually boils a flask of water early in the morning to ensure warm water for the day, preventing the body from chilling with cold water.
Water flasks are incredibly convenient to use. When you want to use it, simply open the flask lid, pour in hot water, and tightly seal it again. To keep the water hot for longer, it's advisable not to fill the flask too full but leave a gap between the lid and the boiling water to enhance thermal insulation.
When using a flask, it's essential to have a stable frame to prevent unwanted external impacts that may cause it to break. When you first purchase a flask, avoid pouring boiling water at 100 degrees Celsius on the same day. Instead, pour water at around 60 degrees Celsius to avoid flask breakage. To ensure the longevity of the water flask, regular cleaning is necessary, keeping it away from places where children often play.
Currently, there are various types and designs of flasks available in the market. However, when purchasing, one must be cautious of low-quality products. It's crucial to select high-quality options, thoroughly examine them before buying to choose the most suitable and durable flask.
A water flask is an incredibly convenient tool in every household. It's a familiar and lovely companion that protects our health every day. Despite the availability of more modern appliances nowadays, the role and utility of a water flask remain extremely important.
