Because cold air rises, very little cold air escapes when you open the top-mounted door of a chest freezer, making it the most efficient style of freezers.
that happens when you open the door and air comes in!
A freezer frosts up when warm, moist air enters the freezer and condenses on its cold surfaces. This moisture then freezes into frost. To prevent frost buildup, make sure the freezer door seals properly, avoid leaving the door open for extended periods, and use a dehumidifier in the room where the freezer is located.
When you open the freezer door, warm, moist air from the surrounding environment enters the freezer. The cold air inside the freezer causes the moisture in the warm air to condense and form tiny water droplets, creating a misty effect. This phenomenon occurs due to the temperature difference between the warm, humid air outside the freezer and the cold air inside it.
To my understanding, on end of the freezer blows air, quite rapidly, towards the other end which acts like a "vacuum". This is called an "air curtain" and acts just as a door would, keeping cold in and heat out.
The outside of a freezer may appear wet due to condensation forming on its surface. This typically happens when warm, humid air comes into contact with the cold exterior of the freezer, causing moisture in the air to condense and collect as water droplets. Additionally, if the freezer door is opened frequently or left ajar, warm air can enter, increasing the likelihood of condensation. Lastly, a malfunctioning door seal could also allow humid air to seep in, contributing to the moisture.
When trying to open the freezer that was recently opened, you will get slight vacuum inside opposing the door opening. On the first opening, some relatively warm air enters the fridge and once the door is closed it is cooled and this causes a drop in pressure that is so called "the suction". When you quickly close the door, the moisture in the warm air is cooled instantly and condenses out. This causes the 'new' air to lose volume creating the vacuum effect. Its a good thing really, as it proves that your door seals are working.
when a cold air front meets a warm air front, the cold air drops as the warm air rises, like what happens when you open your oven when you're baking and when you open your freezer. this combined with a few other variables creates your vortex
Your freezer is full of frost because warm air is entering the freezer and then condensing into frost when it comes into contact with the cold surfaces inside. To prevent this from happening again, make sure the freezer door is properly sealed and closed tightly. Also, avoid opening the freezer door frequently and try not to leave it open for extended periods of time. Additionally, check the temperature settings of the freezer to ensure it is set at the appropriate level.

Frost forms in your freezer when warm air enters and condenses on the cold surfaces. To prevent frost buildup, make sure the freezer door seals properly, avoid leaving it open for too long, and keep the temperature set correctly.
