Does cold absorb heat?
Sort of. In terms of physics, technically there is no such thing as cold. There is only heat, which is than measured on a scale to show how much heat is present. Heat will always transfer to something that has less heat than its present location. So technically no, cold does not absorb heat because cold is a perspective and not something that actually exists.. However, things that have less heat do absorb heat from things with more heat than itself. Cold is an abstract non physics word used to describe things with small amounts of heat, while in reality there is technically at least some measurable amount of heat if compared to true absolute 0 heat.
Why flannel keeps ice unmelted but people warm?
Flannel acts as an insulator, keeping things at the same temperature. It slows down heat transfer with the surroundings. If what you wrap it in is colder than the surroundings, then it will take longer to warm up. If what you wrap in it is warmer than the surroundings, it will take longer to cool down. Ice can stay cold and people can stay warm. The same concept is true for the common thermos bottle - you can keep hot chocolate hot in it or cold juice cold. Note that in the case of people, we are constantly producing body heat from our metabolism so all the flanel has to do in order to keep us warm is to slow the heat transfer to a rate that is less than or equal to the rate at which our bodies are producing heat.
What factor free covection heat flow depends?
The only factor that free convection heat flow depends on is the conductivity of the material. Heat moves toward a cold area and heat it up and the reverse is true for cold, it will cool down something warm.
If the statement If it is cold then you wear a jacket is assumed to be true is its converse If you wear a jacket then it must be cold also always true?
No, the converse of a statement is not always true. In this case, if you wear a jacket, it does not necessarily mean that it must be cold; you may choose to wear a jacket for reasons other than cold temperature, such as fashion or personal preference.
Is it true that On a cold winter day does the heat from inside leak out of the house primarily through the windows?
Yes, windows are a common area for heat loss in a house during the winter. This is because glass is a poor insulator, allowing heat to transfer easily between the inside and outside. Proper insulation and energy-efficient windows can help reduce heat loss.
Why is wind cold?
Wind can feel cold because it removes the thin layer of warm air around our bodies. As the wind blows, it carries away the heat that our bodies generate, making us feel colder. Additionally, wind can increase the rate of heat loss from our bodies, further contributing to the sensation of cold.
Is it true that a hotter object always has a greater amount of heat than a cold object also give example?
yes it is true

Why fingers expand in heat and contract in cold?
They expand in heat to allow blood to reach the extremities to be cooled.. Exactly the opposite is true when there cold.. Blood is drawn away from the extremities to help keep vital organs warmer.
Are reptiles cold blooded true or false?
True - they don't have any way to regulate their own temperature, like mammals do. Instead - they rely on absorbing warmth from a heat source such as the sun (or a heat lamp in captivity).
How heat transfers from a hot object to a cold object - illustration?

True or false males generally do not have barr bodies?
True(:
True or false insulation rated R-35 allows more heat to pass through it than insulation rated R-1?
false
Are reptiles cold blooded true of fulse?
True. All reptiles are cold blooded
Is this statement true or false All diameters pass through the center of a circle.?
All diameters pass through the centre of a circle, is true.
When cold water is poured into a glass the glass becomes colder?
When cold water is poured into a glass, heat energy is transferred from the glass to the water, causing the glass to become colder. The glass loses heat as it transfers it to the colder water until thermal equilibrium is reached.
True or false A heat engine is a device that converts heat into work?
False its not possible to convert all heat into work as some of its being used as energy APEX
