In theory, the cold air would want to slide under the warm air, but it's such a small scale that all that would really happen is there would be an exchange of both warm and cold air, and you'd waste energy in the process. You won't be able to observe very much if you're just opening a door.

When you open a door does hot air go out or coldair come in?

When you open a door, hot air goes out and cold air comes in due to the difference in temperature between the inside and outside of the space. This happens because warm air has a tendency to rise and escape, while cold air tends to move in to replace it.


The inside frame of your front door feels cold during the winter is an example of what heat transfer?

The sensation of coldness on the inside frame of your front door during winter is an example of conductive heat transfer. Conductive heat transfer occurs when there is direct contact between materials at different temperatures, leading to the flow of heat from the warmer material to the cooler one. In this case, the cold air outside is transferring its heat to the inside frame of the door, making it feel cold to the touch.


What causes frost to form on the inside of refrigerators?

Frost forms on the inside of refrigerators when warm, moist air enters the refrigerator and comes into contact with the cold surfaces inside. The moisture in the air condenses and freezes on these cold surfaces, resulting in frost buildup. This can happen if the refrigerator door is opened frequently, if the door seal is damaged, or if the humidity level inside the refrigerator is too high.

What causes a cold draft?

You get a cold draught under your door because the temperature outside of your door is colder then the inside (your room) Draughts are a naturally cold because the room temperature inside a house is mostly always warm or warmish..a draught filters through the bottom of your door and cools the temperature of the room. You get them because 15% of cold air enters though your floor boards..simple solution for this is to get insulation.
