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 wrong to say that heat rises?

It is incorrect to say that "heat rises" because heat does not have mass or volume to physically move in a specific direction. Heat transfer occurs from hot to cold areas due to the movement of thermal energy, known as convection, which leads to the misconception of heat "rising."


Why is it incorrect to say that when a hot object warms a cold one the increase of temperature in the cold one is equal to the decrease in temperature of the hot one?

It is incorrect because the transfer of heat between objects is not a one-to-one exchange. Heat transfer depends on the specific properties of the objects involved, such as their mass, specific heat capacity, and initial temperatures. In reality, some heat will be lost to the surroundings during the transfer process, so the increase in temperature of the colder object will not be exactly equal to the decrease in temperature of the hotter object.


Why is it incorrect to say that an object contain heat?

It is incorrect to say that an object "contains" heat because heat is not a tangible substance that can be stored within an object. Heat is a form of energy that can be transferred between objects or systems. When we say an object is hot, we actually mean that it has a higher internal energy due to the transfer of heat to it.


Why does a carpeted floor feel different to your bare feel than a bare floor feels on a cold morning?

Heat is transferred from the soles of your feet to a cold floor, by conduction. A rug forms an insulating layer, so the temperature of the top surface of the rug will be much nearer your skin temperature. The temperature drop will be through the rug instead of the layers of your skin.


Why its incorrect to say ifa a root is placed horizontally it will bend towards gravity?

It is incorrect to say that if a root is placed horizontally it will bend towards gravity because roots exhibit positive gravitropism, meaning they grow downwards in response to gravity. Thus, a horizontal root would still grow downwards due to gravitropism.

How do you say insulation in Arabic?

It depends on how you mean it. If you are referring to the material you put in walls to keep the heat/cold in when it is cold/hot outside, then it is: Maada 3aazela (مادة عازلة) If you are referring to the idea of protecting someone from outside influences, i.e. Korea had insulation from foreign cultures because of the closed door policy, then it is En3azaal (انعزال)

Does Cold water keep ice cold?

The water would have to be colder than the ice to keep it cold. That is not possible unless it is brine(salt water). Then ice at 32f could be cooled by brine at say 30f.

What causes the heat?

If you have poor insulation in your house/apartment, say by the doors, and windows, that will allow cold air to come in and make the heating get worse. If you can fix where drafts come in, you will improve the heating in your household.
