what is the warm air replacing cold air?

Well, it's still just air, only warmer. Are you asking a weather-related question? None of us are psychic, so who knows. Maybe you're asking about what's known in meteorology as a "warm front."

It's the change in air pressure which causes it.

Igloos inside are warmer than the outside, but this doesn't mean they are above 32ºF.  Since there is no wind inside, heat from the bodies is kept longer (there is little convection) and this creates a samll micro atmosphere inside the igloo. If the air inside goes above 32º, a small layer of ice from the walls can melt, this reduces the temperature close to the walls and again a layer of ice is formed giving back a bit of the internal heat lost during melting.

Advantages: cooling, fresh air. Disadvantages: heat, stale air sickness.

Your body is an engine which continuously produces heat, so it needs to stay in an environment cooler than itself to stay comfortable. \n\nEnergy flows from high to low (or in this case warm to cold), and there are ideal temperatures for your body to operate at. If it's too warm outside then your body can not cool itself as efficiently, so it is uncomfortable. On the other hand, if it's too cold then your body is giving off more heat to the environment than it can generate to keep comfortable. For many people this "ideal" temperature (room temperature) is about 68-72 degrees Fahrenheit, but based on a persons ability to generate heat and their circulation, this value will change.

our bodies constantly generate a lot of heat because of our metabolism. So we have to constantly lose heat to maintain our normal temperature. \n\nIf you put a bucket of warm water outside, and that warm water just happened to be 98.6 degrees Fahrenheit, but the outdoor temperature was 85 degrees Fahrenheit, the water would cool down. That's because the outdoor temperature, while still warm, is cooler than the temperature of the water. Heat naturally flows from warmer places to cooler places. The heat's "goal" is to reach equilibrium–a state where everything is the same temperature as everything that surrounds it. That's why a hot bowl of soup or a cold glass of soda will eventually reach room temperature if you leave them out long enough.\n\nThe difference between you and a bucket of water (well, one of many differences) is that your body is constantly generating more heat. All that heat has to go somewhere, so it tries to escape through your skin. The greater the difference between the outside temperature and the temperature of your body, the faster that heat will escape. That's why you'll feel much cooler on a 60-degree day than on a 90-degree day.

Because the air spreads out, and as it spreads out it retains less heat.\n\nAnd while cold air does sink and hot air rises, as cold air does get lower in altitude it warms up, and hot air cools as it rises. \n\nI live in the foothills west of Denver so I see the rising/falling air thing firsthand. In the winter we get this air that 50 miles to the west was part of a blizzard. As it descends the mountains, it dries out and heats up sometimes bringing temperatures in the middle of the winter into the 60's or 70's.

1. Someone said heat rises - not true. Warm air is lighter than cold air, so warm air rises. The evaporator of the fridge being on top will give a more even 'cold' distribution. If the evaporator was on the bottom, the bottom of the fridge would always be colder than the top.\n2. Cold air is heavier than warm air. If the freezer is open on top, the cold air will not escape. If the freezer is upright, with no doors, the freezer will lose all of it's 'cold' air, it will spill out of the freezer.\n3. Radiation\n4. Pit vipers have an infrared sensor. It picks up the heat generated by the rat's body heat, in the form of radiation.\n5. speed of light.

sure- it's easy- the refrigeration system moves heat out of one area into another- and simple experiment for you to do, is take a can of pressurized spray whatever, and spray it- can gets cold from reduction in pressure, allowing molecules space to "slow down" because they quit "bumping" from being in a tight spot- making room for more heat- or "making" cold- with me so far? now just picture a system with a pump that packs the gas molecules tightly together, and on the other end has a spot for them to expand (making room for more heat)and then runs the "heated" expanded gas through a radiator (heat comes out) and then gets compressed (packed) again- round and round "absorbs heat- moves heat- loses heat" \n hope this helps- if you really need more help email me through answers and I can provide pictures of how it works.

It all has to do with altitude. The higher you are from the earth, the colder it gets. Air is also thinner.

That would be a cold (or at least cool), dry mass of air that originated over a large region of land near the north pole.  (Not over an ocean, unless it was the Arctic Ocean, which is covered by ice.)

A parcel of unsaturated air that rises in the atmosphere will cool by 1C per 100 m.\n\nSo if your parcel is 30C at the surface, it will be 20C at 1000 m.  However, if the water vapor in the air condenses before it has reached 1000 m, the answer would be different (and the answer would depend on the humidity of the air).
