Heat is molecular vibration and can be transfer through eonduction, convection and radiation. Different object had different heat capacity and conduction. We human sense if it is hot or cold from whether we gain or loss heat. In a cold room, walking on cold carpet is still warm because we do not loss much heat to carpet but if we walk on stone or concrete, we loss heat rapidly and we feel it is cloder than carpet even it is at the same temperature.

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 does a stone floor feel cold to the bare foot?
Some substances conduct heat better than others. Things like stone, granite and steel tend to feel cold because they conduct heat away from a bare foot faster and better than, for example, wood or plastic. This is because their particles are more densely packed and hence conduct heat faster. Hence the stone floor feels cold to bare foot( which gives off body heat) as the body heat from the foot will be conducted away quickly. Another reason is due to that feature(conducting heat away quickly for example, from the sun) of the stone floor and the fact that our body produce body heat, it will usually be colder than you body.
How does a cooler use thermal conductivity to keep things cold?
cooler works on the principle of evaporative cooling. Evaporation is the process of converting liquid in to vapour . In this process some part of heat is absorbed and stored (latent heat) resulting in decrease of temperature. We can feel this effect in our daily lives , like sweating in summer gives us cooling effect to body
What does energy feel like to you?
Not all types of energy can be felt. Some can - for example, you can feel heat.
Which travels faster heat or cold?
Heat is energy (of motion), this can 'travel' from 'warm to cold'.Cold is a temperature (absolute or relative to surroundings with higher temperature) and can NOT travel.Temperature is a property of matter, it is not (a kind of) energy.(The same is with 'warmth')
Why is ethanol cold?
It is not cold, the reason u feel ur hand cold when some ethanol reaches it is that it starts vaporizing so it absorbs the heat of ur hand so u feel it cold,

Why does your palm feel cold when you put some acetone petrol or perfume on it?
this is because of inert gases present in perfume

Do living things stay warm?
YES! living things can't be cold or they might freeze to death, yet they can't have too much, either.
What are some antonyms for heat?
cool, cold, freeze
True or false only things that feel warm have heat?
False. Some objects do have heat, but are not always warm. For example, Jupiter has heat but it is not always warm because it doesn't always have direct sunlight from the Sun.
Why high altitude have coldness?
-- There is no such thing as "coldness". There is heat energy. Where there is heat energy, you absorb some of it, and you feel warm. Where there is little heat energy, you lose some of the heat energy you already have, and you feel cold. -- At low altitude or on the ground, you are surrounded by the ground, by dense air, and possibly by bodies of water. All of these absorb and store heat energy efficiently from solar radiation. -- At high altitude, there is no ground nearby holding heat energy, and no bodies of water. Also, the air is less dense, and less able to hold heat energy.
Why does the ice cream feel cooler to the teeth than the ice cold water?
Ice cream feels cooler to our teeth than ice cold water because during the change of state some amount of heat is absorbed which is known as Latent Heat. So in ice no hidden heat is absorbed while in cool water latent heat of fusion or melting is absorbed.
What are some things that are not matter?
Heat
Can cold blooded animals live without heat?
they need heat to be able to do things Heat is relative and anything above 0 kelvins (−273.15 °C or −459.68 °F) is heat. Some micro animals can live in ice, have chemicals inthem so that they do not freeze. In the cold depths of the ocean a lot of spicies, including fish survive happily! What do Eskimo's hunt?
How does one feel cold after talking a hot shower?
When leaving a shower, the body is wet and the air around it is dry. Some of the body moisture starts evaporating into the drier air, removing heat from your body and making you feel cooler.
