Why is ice at 273 k more effective in cooling than water at the same temperature?

 

Ice is more effective in cooling than water at the same temperature because of its lower specific heat. The specific heat is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius. Water has a higher specific heat than ice, meaning that it takes more heat to raise the temperature of water than it does to raise the temperature of ice. This means that when ice and water are both at the same temperature, the ice will be absorbing less heat than the water. As a result, the ice will be able to cool down the surrounding area more effectively than the water.

One of the reasons why ice is so effective in cooling is because of its high latent heat of fusion. The latent heat of fusion is the amount of heat required to melt one gram of a substance. Ice has a higher latent heat of fusion than water, meaning that it takes more heat to melt ice than it does to melt water. This means that when ice is placed in water, it will absorb more heat in order to melt. As a result, the ice will be able to cool down the water more effectively. Another reason why ice is more effective in cooling than water is because of its lower density. Density is the mass of a substance per unit volume. Ice has a lower density than water, meaning that it is less dense. This means that there is more space between the molecules of ice than there are between the molecules of water. This allows the ice to absorb more heat than the water. As a result, the ice will be able to cool down the surrounding area more effectively. Lastly, ice is more effective in cooling than water because it is a better conductor of heat. This means that heat will flow more easily from the hot water to the cold ice. As a result, the ice will be able to cool down the water more effectively.
