"Cold" is a relative term, like "high" or "fast". It does exist as a qualitative term but only for comparison. It doesn't exist as a concrete object.
What else can I help you with?
Why is it incorrect to say that insulation keeps out cold?
Because in science, cold doesn't exist. You can't make cold, you can only remove heat. But in human language we've made words to describe the absences too. Dark is the absence of light. Cold is the absence of heat. Vacuum is the absence of all material. So insulation can't keep the cold out, since the cold doesn't exist. What you can do though is keep the heat in. Heat is a real thing. You can make heat.
Why is it correct to say that ice freezes because of heat?
In chemistry, there is no such thing as "cold", but is renamed "absence of heat." So yes, it is correct to say ice freezes because of a lack of heat.
What is the problem for heat cold and microorganisms?
what is the promble for heat, cold microorganisms
Are shadows made when light is blocked by an object?
No, a shadow is a concept, like cold, which is the absence of another thing (light for a 'normal' shadows or energy for shadows in general, heat for cold). As such, shadows are not made, but exist in areas absent of energy.
When you dip your hand in cold water you feel it cold. Can you name the mode of heat transfer and its direction?
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.
Is heat the absence of cold or is cold the absence of heat?
There is no such thing as "cold" - it's just a concept/term for the absence of heat. Heat and cold are opposite sides of the same coin. You cannot have one without the other. In this sense it is part of any 'heat' engine.
Is 'cold' a kind of energy or is it the absence of heat energy?
There is no such thing as "cold" - it's just a concept/term for the absence of heat. Heat and cold are opposite sides of the same coin. You cannot have one without the other. In this sense it is part of any 'heat' engine.
In what sense do we say there is no such thing as cold?
We say there is no such thing as cold because cold is the absence of heat, just as darkness is the absence of light. Cold is a subjective perception of the absence of warmth, rather than a tangible entity in itself.
What is meant by cold?
The absence of heat.
What is the relationship between cold and heat, and how can we define cold as the absence of heat?
Cold and heat are related in that they are both forms of thermal energy. Heat is the presence of thermal energy, while cold is the absence of heat. Cold can be defined as a lower level of thermal energy compared to heat.
What is source of cold?
Cold is the absence of heat. No doubt about it . . . take away enough heat, and you can make anything cold.
What makes space?
"Space" is one those things like 'cold', 'silence', and 'emptiness', that isn't 'something' all by itself. It's just the absence of something. Silence is the absence of any sound. Cold is the absence of any heat. Space is the absence of any material.
Under the anders celsius theory Is there really such a thing as cold?
No. Cold is not a thing. There is heat, and the absence of heat. NO, only a lack of heat
Why is it incorrect to say the insulation 'keeps out the cold'?

Cold is the absence of heat. Vacuum is the absence of all material. So insulation can't keep the cold out, since the cold doesn't exist. What you can do though is keep the heat in.

Is cartoonnetwork toonface real?
DEfine REal?, is Cold Real or is it the mear absence of HEAT?, is DARKNESS real or just the absence of light? Toonface is real as FACEBOOK is real, and nothing more.
Is heat attracted to cold?
Heat is not attracted to cold. Heat is a form of energy that moves from areas of higher temperature to areas of lower temperature in order to reach equilibrium. Cold is simply the absence of heat.
