yes
the answer is it gets it colder
A Flask
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.

The bone does not actually become hotter, but due to its physical properties it may feel hotter. There is also a difference in how fast the meat and the bone cool down once they are no longer being heated. The heat capacities are different and the meat insulates the bone - which means the bone will stay warmer longer.
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.
styrofoam, but warning fammable and unsafe for the environment!
The boiling point temperature remains constant because liquids evaporate at this point. If the temperature drops the liquid will no longer boil. At a higher temperature the vapor becomes hotter, not the liquid.
Plastic generally does not keep liquid hotter than a foam container or glass container. Foam containers have better insulating properties, making them more effective at retaining heat. Glass containers also have higher thermal conductivity, which can help keep liquids hotter for longer periods compared to plastic.
No, Perfume oils are flammable liquids, and flammable liquids do not last long.
They take longer to get hotter and take longer to get cooler.
Igloo-type cooler.
