Yes, a coolant is a substance (usually a liquid) used to absorb heat.
Water is used as coolant in car radiators because it has high specific heat capacity of 4200 Joules. It has the highest specific heat capacity than any other substance. That is why it is used as coolant in car radiators
Ethylene Glycol.
When a substance is heated up, it emit heat radiation. In such way substance keep on losing heat energy. Thus a way that increase heat losing can lower heat of substance. Water can used as heat absorber.
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
Heat is not a physical substance which can be dissolved.
When an atom splits one of the forms of energy produced may be heat. This heat may be gathered by circulating a coolant substance such as water around or near the radioactive substance to produce steam. The steam is used to drive a turbine and the turbine drives an electical generator.
How the combustibility of a substance influence how the substance is used is, for example: the combustibility of propane infuence how it is used is that you can heat it in a hot air balloon because it releases large amounts of heat.
The reactor coolant is used to extract heat from the nuclear fuel and hence maintains its integrity.
Propane and buetane
I would but there is no way that I can do a diagram
We have no way of doing diagrams, sorry.
"There was no substance to his arguments." "The vapor was without substance." "The substance was a solid powder that seemed to react poorly to heat."
