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.
What else can I help you with?
Where was the thermos derived from?
The thermos was derived from the invention of a vacuum flask by Sir James Dewar in the 1890s. The vacuum insulation technology used in the thermos helps to keep liquids either hot or cold for extended periods of time.
From what language was thermos?
The word "thermos" is derived from the Greek word "therme," which means heat. It was coined around 1907 as a trademark for a vacuum flask that keeps liquids hot or cold.
Does a thermos use thermal energy to keep things warm?
No, a thermos uses insulation to minimize heat transfer through conduction, convection, and radiation. This helps to keep hot liquids hot and cold liquids cold by reducing the rate of heat exchange between the contents and the surrounding environment.
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.
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.
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 temperature in a Thermos?
Actually i dont know ,i am here just like u, to find an answer of this question but thank me that i questioned this question firstlY.
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.
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 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.
What is a bottle that keeps liquids hot in Greek meaning?
Thermos is a Greek word for "hot."
What could you heat water in that would retain the heat the longest?
A vacuum would retain the heat best, hence a thermos flask has a vacuum around it =-)

What is a bottle to keep liquids hot?
a thermos or u can wrap heapes of foil around another bottel
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.
Does a thermos use thermal energy to keep things warm?
No, a thermos uses insulation to minimize heat transfer through conduction, convection, and radiation. This helps to keep hot liquids hot and cold liquids cold by reducing the rate of heat exchange between the contents and the surrounding environment.
