How does a thermos flask keeps a hot liquid hot and a cold liquid cold?
A thermos is able to do what it does by using a several of physical and material properties to keep our hot chocolate hot and our ice tea icy. A thermos has an inner container made of glass. This container is really like one bottle inside of another bottle and sealed at the ends by melting the edges together. The air is removed out from the space between the two bottles to produce a vacuum, which is not a good conductor of heat and does a good job at slowing down the movement of heat. To slow down the other heat they coat the facing surfaces of the glass bottles with a silvery coating (like a mirror). This reflects the heat and helps slow down any losses that might get that way. They use a material like cork or rubber to make the bottle stopper and anything else that might touch the outside surface of the glass container. These materials are bad conductors of heat and slow down the heat loss. What's left is what we can see on the outside which can be metal or plastic and is the covering for the glass bottles. The idea here (with the thermos) is to slow down the movement of heat from one place to the other. So if you have hot stuff in the thermos or cold stuff in the thermos, the end result is the same. Keep heat from moving to where you don't want it to go for as long as possible. NB It's worth mentioning that modern vacuum flasks (Thermos being a trade name) are made almost entirely of stainless steel, inside and out - it doesn't shatter and is naturally reflective, although not polished to a mirror shine when used as a flask inner. Modern stoppers are also made of plastic.
Why did Geisbert and Jahrling smell the flask?
Geisbert and Jahrling smelled the flask to check for any unusual or odorous smell that could indicate the presence or contamination of a dangerous pathogen. Smelling the flask is a part of their safety protocol to ensure that they are not exposed to any harmful substances.
What do each part of the distillation apparatus do?
The boiling flask heats the liquid mixture to create vapor. The condenser cools the vapor back into liquid form. The receiving flask collects the liquid distillate. The thermometer monitors the temperature to ensure efficient separation.
What is the inside part of an envelope called?
The inside part of an envelope is called the "flap." It is the part that is lifted or opened in order to access the contents of the envelope.
What is a vented flask used for?
A vented flask is generally used in laboratory applications to allow gases to escape during heating or mixing processes, preventing pressure build-up. This type of flask helps to control reactions and manage volatile substances more effectively.
What would happen to the mass of the flask and its contents if the balloon was removed?
If the balloon was removed from the flask, the mass of the flask and its contents would remain the same because the air inside the balloon is still part of the system. Removing the balloon does not change the total mass of the system.
Why is sliver used in the inner part of flasks?
A silver coating on the inside of a flask's inner glass container is there to reflect heat back into the liquid.

How do you get an egg out of a bottle?
Invert the cooled flask and place it in the wire gauze without the wire gauze.adjust the egg inside the flask in a vertical position with its pointed side/part directly situated at the entrance leading to the mouth of the flask.heat evenly the wide part of the flask using low flame for a minute. The expected result is that the egf will slowly get outside the flask
How do you get a replacement part for a thermos it has failed after only 1 year?

Describe how you performed the procedure in Part 2 What if your answer should be in paragraph form third person and past tense For example Fifty milliliters of water was placed in the flask not?
Fifty milliliters of water was placed in the flask.
Can you paint a CD?
Yes, but do not write on the back (shiny part)
How does hot water becomes cold in a vacuum flask?
In a vacuum flask, heat transfer occurs through radiation. When hot water is put into a vacuum flask, the vacuum between the inner and outer layers prevents heat transfer through conduction or convection. The reflective barrier reflects heat radiation back towards the liquid, keeping it hot for a longer time compared to a regular container.
Why did Geisbert and Jahrling smell the flask?
Geisbert and Jahrling smelled the flask to check for any unusual or odorous smell that could indicate the presence or contamination of a dangerous pathogen. Smelling the flask is a part of their safety protocol to ensure that they are not exposed to any harmful substances.
How do insulated containers maintain the temperature of the contents?
The inner part of a thermos flask is a seamless container - usually made of glass. It is blown into a mould while the glass is molten - and formed so that there is a thin layer of space between the inside and outside walls. The air between the two layers is sucked out - creating a vacuum. Since heat cannot travel well through a vacuum, the liquid inside the flask stays hot (or cold) for a long time.
How do you get a shiny bagon on ruby?
You have a 1 in 8,192 chance of any wild Bagon you encouter (Bagon are found in the deepest part of Meteor Falls) to be shiny.
How do you get shiny starter in SS?
First: You get to the part where you get the starter. Second: save before you open the present, briefcase, etc. Third: check its summary, and if it isn't shiny, then do step 2-3 again until it IS shiny.
