Is it true that a quantity of ice at zero degrees Celsius must contain less total energy than the same quantity of water at zero degrees Celsius?
Yes indeed. The energy required to change (ice) to (water at the same temperature) is known as the latent heat of fusion. It's an intrinsic property of each substance, and is quite large for water, which is one of the reasons why ice is a preferred substance to use for cooling drinks ... one ice cube removes a lot of heat from the drink in its process of melting.
What is the substance that absorbs and releases heat in a cooling system?
A refrigerant is a substance that absorbs and releases heat in cooling systems.
What are two physical changes that cooling a hot substance may result in?
The substance could liquefy or solidify. Cooling a gas: change from the gas phase to the liquid phase Cooling a liquid: change from the liquid phase to the solid phase
Name the substance which is commonly employed as a cooling agent in the refrigerator?
freon
What must you do to a substance to get it to change its state of matter?
That is done by either heating or cooling.
What are the advantages of cryogenic fluids over other cooling fluids?
cryogenic fluids are - degree temperature means below -4degree Celsius up to -184degree Celsius but in ordinary cooling fluid doesn't having that much of lower temperature
What is room temperature in degrees Celsius in Dubai?
Depends on your central cooling system. The standard room temperature is 26*C.
What is the difference between cooling and chilling?
Chilling is the reduction in temperature of the required solvent below than its wet bulb temperature while the rest is considered as cooling i.e. if we are only reducing the temperature of solvent to an extent such that the final temperature is above its wet bulb temperature than it will be considered as COOLING.

When thermal energy moves out of a substance the temptarue will?
The temperature of the substance will decrease. Scientists refer to the entire process and its effects as "cooling". But my dick is hotter. >:)
Amount of heat necessary to change the state of substance?
Heat of vaporization or enthalpy of vaporization. It is the additional energy, per unit mass, required after vaporization temperature (boiling point) is reached, to accomplish the change in state, from liquid to gas.
What is the substance that absorbs and releases heat in a cooling system?
A refrigerant is a substance that absorbs and releases heat in cooling systems.
Does hot air cool faster then cool air?
The rate of cooling is affected by the temperature difference between the warm substance (air in this case) and the substance that is gaining that heat. If they are close in temperature there will not be as fast am exchange of heat. If the warm air and the cool air in the question are being cooled by transferring their heat to a substance at a set temperature, then the warmer air will cool faster, because it has a bigger temperature differential from the substance than does the cooler air.
How cold can laser cooling get?
It can get near 0 kelvin (-273 Celsius) but not exact 0 Kelvinadd. Currently, the lowest temperature is 170nK, that is 170x10-9K. (Feb 2011)
What is the cooling system of gas turbine blade?
In order to enhance creep life of gas turbine blade, it is required to keep blade at lower temperature, hence internal cooling of blade is done.
Why is there muddy substance on your radiators cap?
This is the result of a dirty cooling system. Corrosion is occuring in the engine block and a cooling system flush is required. Always use a good quality corrosion inhibitor in your cooling system to prevent overheating and possible head gasket damage.
How Freezer Trucks maintain the required temperature?
The same way your refrigerator at home does, just on a larger scale. Cooling system and air circulation.
