In a vacuum temperature is inapplicable. Temperature is a measure of the kinetic energy of the molecules that fill a defined space. In a vacuum there are no molecules so --- no temperature.
In an absolutely perfect vacuum, there is no defined temperature at all. The temperature simply doesn't mean anything. Of course, there isn't really anything that is a perfect vacuum.At very high vacuum, at equilibrium, the temperature will be determined by whatever the container holding the vacuum is in thermal contact with. Something inside an imperfect vacuum isn't at any particular temperature -- if it is at equilibrium, it will be at whatever temperature the things around it are at. However, the rate at which is reaches equilibrium with may be very slow because of the vacuum. If it not at equilibrium, then the object in the vacuum will be at whatever temperature it was set at until it reaches equilibrium with the things around it.
Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.
No, a vacuum by definition is a space with no air molecules present. Therefore, there are no air molecules inside a vacuum.
The inside of a vacuum flask is shiny because of the reflective metal coating, usually made of stainless steel. This shiny surface helps to reflect heat radiation, which helps to maintain the temperature of the liquid inside the flask.
The tightly closed, well-insulated vacuum flask is an example of an isolated system. This is because it does not exchange matter or energy with its surroundings, maintaining the temperature of the contents inside due to the vacuum insulation.
NIL... Does NOT exist...As there is no medium inside the vacuum.
It boils at a lower temperature because of the less energy needed.
No, vacuum-sealed water bottles do not freeze. The vacuum insulation helps to maintain the temperature of the liquid inside, so it will stay at its original state without freezing.
No. The tube inside a thermometer is vacuum. If there was a gas inside, the pressure changes due to temperature changes would cause the liquid inside to expand/contract unevenly.

Yes, a vacuum flask can keep cold liquids cold by creating a vacuum between two layers of insulating material, which helps to maintain the temperature of the liquid inside the flask. This insulation prevents external temperature changes from affecting the liquid inside, allowing it to stay cold for an extended period of time.
The inside of a vacuum flask is typically silver or metallic in color. This reflective surface helps to maintain the temperature of the contents by reflecting heat back into the flask or minimizing heat transfer through radiation.
Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.
Due to open space isolating the flask from external temperature
No, a vacuum by definition is a space with no air molecules present. Therefore, there are no air molecules inside a vacuum.
Glass is a good insulator, helping to maintain the temperature inside the vacuum flask. It is also transparent, allowing users to see the contents of the flask easily. Glass is also odorless and does not affect the taste of the liquids stored inside.
A vacuum is an empty space with nothing inside it.
