, i have recently saw your question and i wanted to answer because it is quite simple to be honest. Some keep the water heated for longer because it all depends on the insulator the better the insulator the more it keeps the water heated for longer. all the insulator is, its a material which acts like a big blanket which simply just traps the hot water steam from escaping or water and it keeps it warm inside. if you just had the bottle without the insulator then the bottle will be cold on the outside which will cause the water to be cold. you cant see the insular when you look in because its tin metal thing on the inside depends what bottle u get and the in the middle form the inside and the outside is the insulator.
i know this since i am a dedicated scientist is inveted many things.
What else can I help you with?
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.
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.
Thermos bottles are used to keep liquid what?
Thermos bottles are generally used to keep liquid from changing temperature for a longer period of time. Usually, one pours hot liquid into the bottle, and it will remain warm for longer, but they are also effective at keeping cold liquid cool.
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.
How do thermos bottles and ice chest keep things hor or cold?
Thermos bottles and ice chests utilize insulation to maintain the temperature of their contents. Thermos bottles typically have a vacuum seal between two walls, which minimizes heat transfer by conduction and convection, keeping liquids hot or cold for extended periods. Ice chests use thick foam insulation and airtight designs to reduce heat exchange, allowing ice to melt more slowly and keeping food and drinks cold. Together, these features effectively preserve the desired temperature of the items inside.
What refers heat?
The root word therm refers to heat, as it does in thermos bottles and thermometers.
What keeps water colder aluminum water bottles or stainless steel water bottles?
Vacuum insulated stainless steel bottles like one from Hydro Flask [see related link "hydro flask" below] or Thermos [see related link "thermos" below] will keep them coldest.
What is a bottle that keeps liquids hot in Greek meaning?
Thermos is a Greek word for "hot."
What is a thermos bottle made out of?
Traditionally, Thermos bottles used borosilicate glass for the vacuum insulator, with a plastic or metal envelope. Modern Thermoses are typically made entirely of steel.
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.
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.
What refers to heat in atoms and chemistry?
The root word therm refers to heat, as it does in thermos bottles and thermometers.
