Air traps heat by absorbing and storing the heat energy that radiates from the Earth's surface. This is because certain gases in the atmosphere, such as carbon dioxide and water vapor, are capable of absorbing infrared radiation, thereby trapping heat and preventing it from escaping into space. This phenomenon is known as the greenhouse effect.

What l doesn't conduct heat very well?
Air is a poor conductor of heat. It has low thermal conductivity, which means it does not transfer heat efficiently. This is why materials like wool or fiberglass that trap air are good insulators.
How do Cotton balls reduce heat loss?
Cotton balls trap pockets of air, which is a good insulator and helps reduce heat loss by preventing the transfer of heat between surfaces. This air acts as a barrier to prevent heat from escaping, keeping the area warm.
Which fabric is the best heat insulator?
Wool is considered one of the best heat insulating fabrics due to its natural properties that trap air, creating a barrier against heat loss. Other good heat insulators are fleece and down feathers, which have a high loft and trap warmth effectively.
What materials are good insulator of heat?
Materials that are good insulators of heat include wood, fiberglass, polystyrene foam, and aerogel. These materials trap air and prevent the transfer of heat due to their low thermal conductivity. Additionally, materials like wool and cotton can also act as good insulators due to their ability to trap air and prevent heat loss.
Which is the better heat insulator?
Materials with low thermal conductivity are better heat insulators, such as fiberglass, foam, or aerogel. These materials trap air or have high resistance to heat flow, hence reducing heat transfer.
What air traps heat and causes the greenhouse effect?
Greenhouse gases such as carbon dioxide, methane, CFC's, and water vapor trap trap the heat in the Earth's atmosphere.
Will a glass window attract heat and trap it?
YUPPERS! and it will trap most of it but not all 2nd Answer: Ummm . . . a glass window does not attract heat. It does not 'trap' it, either. The glass may allow heat through, or glass can heat up, itself, but then it can radiate that heat away when the air around the glass is cooler than it is. That is certainly not, "Trapping" the heat.
Which materials are best at keeping you warm?
Ones that are good insulators of heat or can trap pockets of air to insulate as air is a terrible conductor of heat. E.g. Polystyrene
How does curtains and carpets reduce heat loss?
curtains trap the cool air in between the hotter air carpets trap the cool air in the fine fibres
What is the direct object in the sentence plants trap the sun's heat?
The direct object of the verb 'trap' is the noun heat(plants trap heat).
What is the atmosphere and why does it trap haet?
Atmosphere is the blanket of air around the earth. It traps heat for maintaining the temperature.
What l doesn't conduct heat very well?
Air is a poor conductor of heat. It has low thermal conductivity, which means it does not transfer heat efficiently. This is why materials like wool or fiberglass that trap air are good insulators.
Why is wadding or filling a good insulater?
Wadding, or filling, will trap pockets of air. As the air is trapped, it cannot convect heat so easily, and it is also more difficult for heat to be conducted. So, trapped air is a good insulator.
How can you prevent heat loss by using air gaps insulation and shiny surfaces?
Air gaps can trap pockets of still air, which is a poor conductor of heat, reducing heat transfer. Shiny surfaces can reflect heat radiation, reducing heat loss. By combining these two insulation techniques, you can effectively prevent heat loss in a space.
How do Cotton balls reduce heat loss?
Cotton balls trap pockets of air, which is a good insulator and helps reduce heat loss by preventing the transfer of heat between surfaces. This air acts as a barrier to prevent heat from escaping, keeping the area warm.
