Heat can cause expansion of materials, increase in molecular movement, and chemical reactions to occur more readily. Cold can cause contraction of materials, decrease in molecular movement, and slow down chemical reactions. Both heat and cold can impact the physical, chemical, and biological properties of substances.
What else can I help you with?
Does a refrigerator change heat into cold?
No, a refrigerator does not change heat into cold. It removes heat from inside the refrigerator and releases it outside, resulting in the cooling effect inside the refrigerator.
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.
Why you feel cold when you are wet?
When water comes in contact WITH YOUR Body, it absorbs heat from your skin and evaporates. Since heat is absorbed from your skin, you feel cold, just like when an ice cube comes in contact with your skin.becose the watter wold mix with the air
Do cold things have heat?
No, cold things do not have heat. Heat is a form of energy that is transferred from hot objects to cold objects. Cold objects have less heat energy compared to hot objects.
In which direction does heat flow: from hot to cold or from cold to hot?
Heat flows from hot to cold.
Does a refrigerator change heat into cold?
No, a refrigerator does not change heat into cold. It removes heat from inside the refrigerator and releases it outside, resulting in the cooling effect inside the refrigerator.
What is the effect of a eclipse?
It gets dark and cold(because there isn't any light or heat from the sun)
Do cold radiation waves go down?
There is no such thing as cold radiation. Cold is nothing in itself; it is merely the absence of heat - or just less heat. Heat, like light, radiates, but cold, like darkness, does not.What you may think of is cold convection; i.e., the fact that cold air will sink and warm air will rise. This effect is often confused as being 'cold radiation'.
How do strong winds and long cold winters effect the tundra's population?
helps plants retain heat
How does air movement effect climate?
because winds move heat and cold temperatures from one place to another
Is it good if there is a heat wave in effect you've got a fan on medium but 3 feet from you and you're freezing cold?
no it is not
Is activation of a cold pack endothermic?
Yes, the activation of a cold pack is endothermic. It absorbs heat from the surroundings in order to lower the temperature of the pack and create a cooling effect.
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 the name of the cooling effect for moving air at different temperatures?
The cooling effect is called the wind chill effect. It is the increase in the rate of heat loss experienced by a body due to the combination of wind and cold temperatures.
Do cold things have heat?
No, cold things do not have heat. Heat is a form of energy that is transferred from hot objects to cold objects. Cold objects have less heat energy compared to hot objects.
In which direction does heat flow: from hot to cold or from cold to hot?
