"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.
Our body is used to a specific normal amount of heat. Heat, is the energy of a particle, so if a particle has a high energy amount, it will vibrate more, which makes it appear hotter to us. So, in essence, heat is the amount of energy in an object.
That said, cold is just a lower energy amount in a particle than we're used to, which makes it feel cold to us. So, it is the absence of heat, which is energy. That's why absolute zero is the lowest temperature an object can have.
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.

The absence of heat.
Temperature is an indicator of heat or cold. Cold is the absence of 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

The definition (at least scientific) of cold is the absence 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.
