What else can I help you with?
Two kittens are sleeping by a furnace vent. They are relying mainly on what kind of heat transfer?
Radiation warming
When huddling do penguins keep warm by radiation conduction or convection?
Penguins keep warm when huddling mainly through conduction, as they transfer body heat to one another by physical contact. Some heat transfer can also occur through convection, as warmer air rises within the huddle, creating a circulation that helps distribute heat more evenly. Radiation plays a minor role in this process.
Why do you think the thermos bottle contains a vacuum or space from which the air has been removed?
The vacuum or empty space in a thermos bottle helps to minimize heat transfer by convection and conduction. Without air molecules to transfer heat, the vacuum acts as insulation to keep the contents either hot or cold for an extended period.
Why do convection and conduction not happen in a vacuum?
All of those heat transfer methods require a medium - gas, liquid or solid. Heat is transferred from warmer molecules to adjacent cooler ones in conduction. Heat is transferred by moving gas or liquid in convection/advection. Space is essentially a vacuum. Molecules are not dense enough to transfer heat to one another, there is not a dense enough gas to convect - leaving only radiation as the heat transfer method.
Vacuum is mantained in thermos flask?
A vacuum is maintained in a thermos flask in order to prevent heat transfer by conduction and convection. The absence of air molecules in the vacuum reduces the amount of heat that can be transferred through these processes, helping to keep the contents of the flask hot or cold for longer periods of time.
What is the basic principal involved in a woolen blanket?
A woolen blanket is a good thermal insulator. Actually, air is among the very best of thermal insulator, and the wool fibre /fibreglass fibres, macerated paper, porous foam) serves to keep the air from moving and thus losing heat. Heat could be lost by radiation, conduction, and convection (a special case of conduction and convection combined.). Not of great importance in a blanket, but of importance in clothing is the fact that wool does not absorb water easily.
Is wool a good insulator of heat?
yes it is because wool has air pockets which keep in all the heat and block out the conduction of heat, convection and radiation.

Can you keep a blanket from the airplane"?
No, you cannot keep a blanket from the airplane.
How are conduction and convection similar?
Well, isn't that a happy little question! Conduction and convection are like two friends helping each other out. They both involve the transfer of heat, but in slightly different ways. Conduction is like passing the heat from one molecule to another, while convection is like a warm hug spreading through a fluid or gas. Just remember, they both work together to keep things cozy and balanced.
How do flasks keep drinks hot?
Flasks keep drinks hot by utilizing a vacuum-sealed design that prevents heat transfer. The vacuum layer acts as insulation, reducing heat loss or gain. In addition, the flask is usually made from materials with low thermal conductivity to further minimize temperature changes.

How does a blanket keep wrapped ice as ice for a long time?
I think its because of pressure on the ice
Why does a blanket keep us warm?
It helps you keep warm but not by giving you heat (thermal energy). You give the blanket heat and it helps keep your heat in. This is also true among other warm things you wear or use when you need to keep warm like coats,blankets,sweaters,etc...
