"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.
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.
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 promble for heat, cold microorganisms
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.
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.
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.

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.
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.
Cold is the absence of heat. No doubt about it . . . take away enough heat, and you can make anything cold.
"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.
No. Cold is not a thing. There is heat, and the absence of heat. NO, only a lack of heat

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.
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.
