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.

What is the temperature in a vacuum?

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.


What are examples of a vacuum?

Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.


Are there many of air molecules inside a vacuum?

No, a vacuum by definition is a space with no air molecules present. Therefore, there are no air molecules inside a vacuum.


Why is the inside of a vacuum flask shiny?

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.


A tightly closed well-insulated vacuum flask is an example of which type of system?

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.

What is room temperature and pressure?

NIL... Does NOT exist...As there is no medium inside the vacuum.


Does water inside a vacuum boil at a higher or lower temperature than it does under normal pressures?

It boils at a lower temperature because of the less energy needed.


Do vacuum sealed water bottles freeze?

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.


Is there inert gas inside a thermometer?

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.

Can a vacuum flask keep cold liquids cold?

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 color of a vacuum flask in the inside?

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.

How does a vacuum flask reduce heat loss from a hot liquid inside?

Due to open space isolating the flask from external temperature

Why are the walls of the vacuum flask made from glass?

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.


In a vacuum there's no what?

A vacuum is an empty space with nothing inside it.
