Ice at 273 K is more effective than cooling water at the same temperature because it requires more energy to melt ice into water than to simply raise the temperature of water. This process, known as the latent heat of fusion, absorbs a significant amount of heat from the surroundings, making ice a more efficient cooling agent. Additionally, ice can maintain a lower temperature than water due to its phase change properties, allowing it to cool substances more effectively.

What is the great cooling effect produced by water evaporating, and how does it relate to its high evaporation rate?
The great cooling effect produced by water evaporating is called evaporative cooling. When water evaporates, it absorbs heat from its surroundings, causing a cooling effect. This cooling effect is related to water's high evaporation rate because the faster water evaporates, the more heat it can absorb, leading to a greater cooling effect.
Is it better to point a fan in or out for optimal air circulation and cooling?
Pointing a fan out is better for optimal air circulation and cooling. This helps to expel hot air from the room and bring in cooler air from outside, creating a more effective cooling effect.
Is it better to have a fan blow in or out for optimal air circulation and cooling?
For optimal air circulation and cooling, it is generally better to have a fan blow out. This helps to expel hot air from the room and draw in cooler air from outside, creating a more effective cooling effect.
How is the properties of water glycerol and oil compaired to the properties of the liquid in radiators?
The more vigorously they oscillate, the more energy they have, the hotter the metal (more heat). If the metal is heated too much, the atoms oscillate too vigorously to stay at their fixed positions hope this helps :-)
Why does a desert cooler cool better on a hot dry day?
In a desert cooler, the water inside it is made to evaporate. This leads to absorption of energy from the surroundings, thereby cooling the surroundings. Again, we know that evaporation depends on the amount of water vapour present in air (humidity). If the amount of water vapour present in air is less, then evaporation is more. On a hot dry day, the amount of water vapour present in air is less. Thus, water present inside the desert cooler evaporates more, thereby cooling the surroundings more. That is why a desert cooler cools better on a hot dry day.
Why is a piece of ice more effective in cooling a drink than the same mass of cod water?
A piece of ice is more effective in cooling a drink because it has a higher specific heat capacity than cold water, meaning it can absorb more heat while melting without significantly increasing in temperature. As the ice melts, it draws heat from the drink, cooling it more efficiently than cold water, which has already reached a stable lower temperature.
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.
How effective is a PC with a water cooler in maintaining optimal performance and temperature levels during intensive tasks?
A PC with a water cooler can be very effective in maintaining optimal performance and temperature levels during intensive tasks. Water cooling systems are more efficient at dissipating heat compared to air cooling, which can help prevent overheating and maintain consistent performance.
Why is ice at 273k more effective in cooling than the water at the same temperature?
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.
Ice at 0 degrees celsius is more effective in cooling than water at 0 degree celsius?
Ice can absorb more heat when melting into water at 0 degrees Celsius compared to water at the same temperature, making it more effective at cooling. This is because the process of melting ice involves absorbing additional heat energy from the surroundings to break the bonds between ice molecules into liquid water molecules.
who is heat sink dry soil or water?
A heat sink is a device that absorbs and dissipates heat generated by electronic components. In the context of cooling systems, water is a more effective heat sink than dry soil due to its higher thermal conductivity and heat capacity. Water can carry heat away more efficiently, making it a better choice for cooling applications.
Which is more effective for filtering water, coke or charcoal?
Charcoal is more effective for filtering water than coke.
Why is the cooling water in the liebig conden ser made to run counter current to the flow of the distillate?
Running the cooling water in the Liebig condenser counter-current to the distillate flow improves the condensing efficiency by maintaining a larger temperature difference between the vapor and the cooling water throughout the length of the condenser. This allows for more effective heat transfer and a higher rate of condensation.
How humidity affects the water cooling process?
When water can evaporate, the absorption of heat by the vaporizing water adds a significant amount of cooling. When the ambient humidity is already high, less water can evaporate before the air become saturated with water vapor and consequently cooling is more difficult. When ambient humidity is low, more water can evaporate before the air becomes saturated with water vapor - and thus more cooling can occur for the same flow rate of water.
What is the great cooling effect produced by water evaporating, and how does it relate to its high evaporation rate?
The great cooling effect produced by water evaporating is called evaporative cooling. When water evaporates, it absorbs heat from its surroundings, causing a cooling effect. This cooling effect is related to water's high evaporation rate because the faster water evaporates, the more heat it can absorb, leading to a greater cooling effect.
What is disadvantage of water cooling system?
heavier and more complex
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.
