It insulates the heat of your body temperature in the bag.
When a chip bag gets warm from the sun, the air inside the bag expands, which can cause the bag to puff up or inflate. This is due to the increase in temperature causing the air molecules to move more rapidly. As the bag cools down, the air inside contracts back, causing the bag to return to its original shape.

A porous bag is a bag that has small holes in it, allowing the powders or leaves or whatever is inside it to come out. A tea bag is a porous bag.
When a sealed bag is compressed, the air inside the bag gets more tightly packed, which increases its pressure. Even though the volume of the bag may decrease due to compression, the air molecules inside become more densely packed, leading to increased pressure.
If it hasn't been opened, the air particles inside gain kinetic energy, meaning that the bag will expand and eventually pop. Then the sun's heat is transferred into the particles of the bag, and so the particles move apart, melting the bag. If extreme heat, the bag may face sublimation. (Looking at the particle matter through the particle theory of matter.)
To ensure a comfortable and warm night's sleep in a dry down sleeping bag, consider the following tips: Use a sleeping pad underneath for insulation from the cold ground. Wear dry and warm clothing to retain body heat. Ventilate the sleeping bag if you start to feel too warm. Keep the sleeping bag dry by avoiding moisture and condensation. Fluff up the down filling to maintain its loft and insulation properties.
It traps your body heat inside the bag.
That depends on the sleeping bag itself. Any sleeping bag that is made for camping in un-harsh conditions would not keep you warm enough in mountain areas.
Not usually. It is rather bad for the sleeping bag, but it shouldn't ruin it. Just dry it and try to get it "fluffy". If it does, it should still keep you warm effectively. If you want to be sure, just try it out.
Sleeping Bags don't actually provide the heat, it is when our body heats us and he bag insulates (keeps) the heat in the bag. That is why we can get constant heat from the bag.
Yes, a waterproof sleeping bag is suitable for camping in rainy conditions as it will help keep you dry and warm.
Down traps a lot of air, and air is a good insulator.
The type of sleeping bag that you will need to get will greatly depend on the elements or weather conditions you will be camping in. I have found that a down filled sleeping bag is light to carry but can be very good for keeping warm.
This will depend on the climate where the children will be sleeping. You should match the location with the bag's temperature rating, the child's metabolism, the bag's weight, etc.
depends on the sleeping bag, MEC bags are usually duck down, but some are goose.
The mummy bags where just your face shows. Keep out the bugs, snakes & scorpions & are very warm.
The recommended sleeping bag for camping in cold weather should have an R value of at least 4. This will provide sufficient insulation to keep you warm and comfortable during chilly nights outdoors.
