Why is cooling with ice more effective than cooling with water?

Ice takes a considerable amount of energy just to melt down to the 273k water. Hence, it can cool down whatever you want to cool down more effectively.

∙ 12y ago- Water changes to ice at 0 degree C.In this change,heat is released so as to gain the suitable temperature for freezing.While in case of ice changing into water,the water releases the chillness so as to be a liquid.So, ice at 273K is more effective than water at the same temperature.

∙ 14y ago"Cooling" occurs when the substance being cooled (let's call it the "coolee" transfers some of its heat to the substance doing the cooling (the "cooler). Any time the cooler's temperature is lower than the coolee's the coolee's temperature will decrease, until the cooler and coolee have the same temperature.
If the cooler is a solid (like ice), at the melting point (0oC), then it is, of course, the same temperature as water at the freezing point, so it would seem that they would cool the coolee equally well. However, the ice cannot warm to above freezing until it is completely converted to water. And it takes a great deal of heat to melt ice. All of this heat is coming from the coolee.
Or look at it this way. Though ice and water, if both at the melting/freezing point, share the same temperature, the water actually contains far more heat energy than the ice. The ice, with less heat energy, can extract more heat from the coolee than the water can.

In other words, ice has less heat than water at the same temp.
Wiki User
∙ 11y agoice is more effective because during the process of boiling it has absorbed more heat equal to its latent heat of fusion
Wiki User
∙ 12y agoAt 273K ice must absorb heat (approximately 6 kJ/mol) in order to melt before any temperature change can take place. Liquid water at the same temperature already has this amount of energy.
Wiki User
∙ 11y agoBecause melting of ice absorb plenty of heat in the form of latent heat
Wiki User
∙ 11y agoBecause this temperature is lower than the room temperature.

ice
because when water changes to ice it releases heatso as to gain a suitable temperature

Why is a piece of ice more effective in cooling a drink than the same mass of cod water?
Because the ice is colder than cold water.
Ice at 0 degrees celsius is more effective in cooling than water at 0 degree celsius?
Yes, becasue of the latent heat, which is approx 80 cals per gram.
Is tepid water better for you to drink than cold water?
There are different opinions concerning this topic because their effects are somewhat different. But majority agree that tepid water is more effective than cold water. You can read their effects in detail here: http://scienceray.com/biology/ecology/drinking-cold-water-or-warm-water-which-one-is-more-effective/
Why cooling effect of ice at 0 degree Celsius is more than same amount of water at 0 degree Celsius?
Water at 0 oC is ice.
Which causes more cooling ether or water?
Assume question is about evaporative cooling rate Ether had vapour pressure of around 0.7 ATM it would be readily evaporate in air. The ether would be a lot colder than water and cause higher cooling rate. However, if the matter talk about conduction cooling or cooling per unit mass it might be different answer from above.

What are some of the advantages of water cooling?
Water cooling keeps your system cooler if you are constantly overclocking it. It does it far better than air cooling. However, the price for water cooling is higher than air cooling.
Water and ether are placed on the palms of both the hands which will cause more cooling ether or water?
Ether has a greater cooling effect than water when smeared on your hands because of its evaporation method. Ether gets its energy from your hands. So when it evaporates, the cooling effect is greater than water.
Is solar heating of water more cost effective than electricalof water?
Solar water heating is generally more cost effective than an electrical water heater. Though solar water heaters usually have a higher initial investment if commercially purchased.
Is the lemonade diet more effective than just drinking water?
No. Nothing beats water.
What are the warming and cooling tendencies of land and water?
The land cools down quicker than water also it takes more time for warming water in a water body than land.
What are differences in heating and cooling rates of land and water?
How do the heating and cooling differences between land and water affect us? ...
Can you drive a car with only water in the radiator?
Yes, you can. In fact, pure water is a more effective coolant than any mixture of water and antifreeze. However, it is not recommended that you run pure water in a cooling system for an extended length of time. Not only does antifreeze protect against freezing. It also contains corrosion inhibiters, which help prevent your engine and radiator from succumbing to corrosion. For these reasons, using only water in your cooling system is something you should do only when you have no choice (such as a roadside emergency). However, if pure water is used in a cooling system for this reason, the cooling system should be drained ASAP and refilled with the proper mixture of antifreeze and water.
How does the heat of water help maintain the temperature of earth?
By heating and cooling more slowly than land or air
How does a ceramic butter dish with a water reservoir beneath it keep butter cooler than one without?
Evaporative cooling - the water evaoprates and chills things slightly as it does so. (Doubt its very effective though)
