What is the process of purifying volatile substances?
The process is called sublimation in which the substance is vaporized and then condensed by a cooling condenser.
Why water is the best substance for cooling down object?
Water is very commonly used as a coolant for two reasons. First, it has a very high specific heat, meaning it can absorb a large amount of energy while not increasing in temperature as much as other substances. Second, it is very abundant on Earth and is easily accessible.
What is a specific example of a rock formed by molten material cooling?
Granite, rhyolite, obsidian, basalt, pumice, gabbro, diorite; all examples of igneous rock that by definition forms from the cooling of molten rock.
What substances does the body need when exercising?
The body mostly needs fats which are used to produce energy. The body also needs water which is used for cooling and other important functions.
How could you change the viscosity of the substances?
Cooling a fluid increases the viscosity. Otherwise, to thicken it or increase the viscosity, requires the addition of another chemical.
Do metals expand when they are cooled?
No, most substances contract with cooling, only some exotic substances (eg water) expands when cooled.
How do you determine the specific heat capacity of an object by method of cooling?
the spesific heat capacity of a liquid by the mithod of cooling
What is the process of purifying volatile substances?

Do pure substances cool quicker than non pure substances For example pure water and salty water?
The impurity of a substance may enhance or decrease the rate of cooling, according to its chemical properties.
Why water is used as a cooling agent?
It is cheap, has a high specific heat, and low viscosity.
Why copper pipesare used in ac work?
Copper has a .39 specific heat capacity which is almost the same as silver, but is 1/6 the cost. Specific heat capacity is a substances ability to hold heat and the smaller value the better. Copper is the 4th best solid to use for cooling systems behind lead, silver, and gold(none of which can be used for expense and/or health reasons.)
Which type of mineral formation involves the cooling of magma?
A rich assemblage of silicate-based minerals forming the igneous rocks that are solidified from magma. The faster the cooling the finer the crystals but the minerals are the same for a specific eruption or intrusion irrespective of cooling rate.
How do you determine the specific heat of any two liquids by using newton's law of cooling?
Newton did not provide a "law of cooling". You must be thinking of something else. Please restate the question.
What is the difference between Cooling Energy and Cooling Load?
Cooling energy depends on the efficiency of cooling device used but cooling load depends on many factors such as the volume of the room, comfort band, fabrics used, geographical and climatic properties of location that the room is built. In simple terms, for a room with a specific cooling load different devices can be used. Since, each device has different efficiency, therefore different amounts of cooling energy may be obtained.

What influences radiational cooling?
Properties of the material such as thermal conductivity, specific heat, and emissivity, and the temperature of the surroundings.
What system cooling device has the most features?
Anticair have some cooling devices that offers multiple channels and temptures. There are some that offer memory control so it will automatically set to a specific temp that you are looking for.
