How much time there is hot in Thermos Flask?
The duration that hot liquids stay hot in a thermos flask depends on several factors, including the quality of the thermos, the initial temperature of the liquid, and the surrounding environment. Generally, a well-insulated thermos can keep liquids hot for anywhere from 6 to 24 hours. High-quality models may even maintain temperatures for up to 48 hours. It's best to check the manufacturer's specifications for precise duration estimates.
How fast does water cool down in a thermos after boiling?
The rate at which water cools down in a thermos after boiling depends on several factors, including the thermos's insulation quality, ambient temperature, and the initial water temperature. Generally, a well-insulated thermos can retain heat effectively, cooling the water only a few degrees within the first hour. Typically, water may cool down to around 70°C (158°F) after about an hour, but this varies based on the specific thermos design and conditions.
Why does thermos bottles advertised as good for 24 hours while others are claimed to be able to keep liquids hot or cold for 48 hours?
The claim of 24 hours versus 48 hours typically depends on the insulation quality and thickness of the materials used in the thermos bottle. Thicker insulation and higher-quality materials can help a bottle retain temperature for a longer period. Different designs and technologies might also impact how long a bottle can keep liquids hot or cold.
What is the typical thermos made of?
Thermoses are typically made of stainless steel due to its durability and ability to retain heat effectively. Some thermoses may also have a layer of glass or plastic on the inside to further insulate and maintain temperature.
What will be the temperature in 24 hours when the germinate seeds in the thermos flask?
The temperature of the germinating seeds in a thermos flask in 24 hours will depend on several factors, including the initial temperature of the seeds, the ambient temperature, and the insulation quality of the thermos. Generally, thermos flasks are designed to maintain temperature, so the seeds may remain warm if they were initially heated. However, without specific data on these conditions, it's difficult to predict the exact temperature after 24 hours.
Why does my Thermos not keep liquids hot?
Your Thermos may not be keeping liquids hot due to issues with insulation, such as a broken vacuum seal or thin wall construction. Additionally, if the Thermos is old or damaged, it may have lost its ability to retain heat effectively. It is also possible that the cap is not tightly sealed, causing heat to escape.
Why do liquids retain their teperature in a thermos?
substances cool as they lose heat energy, and get warmer as they gain heat energy. A thermos is an insulated container which opposes the movement of heat, thus hot liquids lose heat to the cooler outside more slowly and stay hotter for longer and cold liquids gain heat from the outside more slowly and stay colder for longer.
Can thermos flasks keep cool things cold?
Yes, thermos flasks are designed to keep liquids cold by insulating them from the surrounding temperature. They typically have a vacuum-sealed layer that prevents heat transfer, helping to maintain the cold temperature of the liquid inside.
In terms of molecules moving how a does a thermos bottle keep hot liquids hot and colds liquids cold?
If you look inside of a thermos you will see metal. This absorbs the heat or the cold and keeps it that way for as long as the contents are in the thermos.
What feature of a thermos does not limit heat flow?
Vacuum insulation is a feature of a thermos that does not limit heat flow. By creating a vacuum between the inner and outer walls of the thermos, heat transfer through conduction and convection is minimized, allowing liquids to maintain their temperature for longer periods.
Can a thermos or glass cup keep liquids hotter longer?
Yes, both a thermos and a glass cup can help keep liquids hotter for longer periods of time compared to a regular open container. This is because they have better insulation properties, reducing heat transfer between the liquid and the surrounding environment.
What is the job of a thermos?
A thermos is designed to keep beverages hot or cold for an extended period of time by providing insulation that minimizes heat transfer. It works by creating a vacuum-insulated chamber that prevents heat from escaping or entering the container, maintaining the desired temperature of the liquid inside.
When is a thermos too old?
A thermos is too old when it shows signs of wear and tear such as cracks, dents, or rust that may affect its ability to properly insulate and retain temperature. It is also advisable to replace a thermos if it has been used for an extended period of time and no longer maintains the desired level of thermal performance.

What is a Greek rooted word which means a container intended to retain the heat of a liquid?
A Greek-rooted word which means a container intended to retain the heat of a liquid is thermos.
