Cloth is a bad conductors/good insulator of heat. Bad conductors keep things warm or cold, so the answer is, because cloth is a bad conductor of heat!
Hot things get cooler, and cold things get warmer, because they exchange heat with their surroundings. A "cool bag", whatever that is, is apparently designed in such a way as to prevent that (probably it's insulated).
Insulation works by slowing down the transfer of thermal energy between two spaces. This means it can keep hot things hot and cold things cold by reducing the amount of heat that moves in or out of the insulated space. Materials like foam, fibers, or gases are commonly used as insulators to trap heat or cold air inside and maintain the desired temperature.
No, cold things do not have heat. Heat is a form of energy that is transferred from hot objects to cold objects. Cold objects have less heat energy compared to hot objects.
No, a thermos uses insulation to minimize heat transfer through conduction, convection, and radiation. This helps to keep hot liquids hot and cold liquids cold by reducing the rate of heat exchange between the contents and the surrounding environment.
Hot things contain more energy compared to cold things. This is because the temperature of an object is directly proportional to its energy content - hotter objects have more kinetic energy in the form of faster moving particles. Thus, hot things require more energy to maintain their temperature compared to cold things.
Yes, it can also keep things cold.
A thermos will generally keep either a hot item hot or a cold item cold. you can use them for things like cold drinks, soup, hot chocolate, or pretty much any liquid you want to keep the same temperature.
Yes it would as insulators keep in the heat and keep it out depending on whether the item is hot or cold.
A thermometer
They Keep out cold and keep in hot or keep in cold and keep out hot it depends on the weather
You can put hot things in the refrigerator. But the main job of the refrigeratoris to "refrigerate" ... take heat away from hot things and make them cold. Sothe hot thing that you put in there won't stay hot, unless it's in an insulatedcontainer. Otherwise, it'll turn into a cold thing.
Keep hot foods hot, and keep cold foods cold.

by black marks do you mean blackheads? If yes fill a bowl with hot water soak a face cloth in and place on your nose keep the cloth as hot as possible and do for at least 10 minutes rub the cloth around the nose for a few minutes then place a cold wet cloth on your nose for a few minutes. the first process with the hot cloth will open the pores rubbing your nose will remove the dirt and the cold wet cloth will close the pores, resist the urge to squeeze a week of this treatment once per day should cure the problem
It keeps the air trapped in side and has to layers with air as insulation in the middle
