Because the movement of the gas-molecules inside the freezer are smaller, and therefore, that more molecules are present in a given volume inside the freezer.. If the temperature of the air outside the freezer, was the same as inside the freezer, the air outside and inside would have the same density - roughly said - because the humidity inside the freezer also plays a role. But in general the above is enough to answer your question.
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
At the center of a black hole is a mass that has collapsed to an infinitely dense point.
dense
Balloons that are filled with hot air, hydrogen, or helium will float, or rise upward, because the less-dense gases inside them are displaced by the heavier air around them. Balloons will only rise until the gas density inside them is equal to the density outside. In the case of helium balloons, this may be above the elastic limit of the balloon, and it will pop or leak.
It is called the nucleolus. It is in the nucleus
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
Dense gas is pumped through small holes within a metal tube, by a motorized "compressor." When this gas makes contact with the metal on the inside, it has a cooling effect and the metal absorbs the heat from the air on the outside of the tube. Once the heat has been absorbed, this air is pumped in, or cycled through the fridge and freezer to keep things cold.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
The air is less dense than the air outside.

No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.
Warm air is less dense and tends to rise, cool air is more dense and tends to sink. That is why a hot air balloon rises if the air inside is warmer than the outside air.
A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.

The freezer compartment is often located at the top of a refrigerator because warm air is less dense than cold air. The cooled air from the freezer compartment goes down, thus it is not lost.
Both because outside the machine insulator its plastic and the inside of the machine metal I hope you understand
Yes. By definition, most gases are less dense than most solids. i can't think of a counter example. Plus, the gas inside a hot air balloon is superheated to make it even less dense, as heating things makes them less dense
