Why does melting ice cool an orange?
Because the ice is at lower temperature than the ice-cold water. Because melting ice has a lower specific heat than ice-cold water.
Why does a piece of ice at 0 C cools a drink more effectively than the same mass of cold water at 0 C?
Answer: Ice is more effective in cooling than water at the same temperature because ice can absorb latent heat as well as the heat energy in order to attain room temperature. Water at 0 C can absorb heat energy only to attain the room temperature.
Why do drinks get cooled quickly by adding pieces of ice rather than the ice-cold water?
Drinks get cooled more quickly by adding pieces of ice at 0oC than the ice-cold water at 00C : This is because 1 g of ice at 0oC takes 336 J of heat energy from the drink to melt into water at 0oC. Therefore cooling produced by 1 g ice at 0oC is more than that by 1 g water at 0oC.
Why is ice effective at cooling drinks?
Because ice molecules move slowly and cluster tightly together, they produce a relatively low amount of heat. In other words, ice absorbs heat from the water. As the water molecules lose energy, they begin to slow down, and consequently to cool.
What is more effective in cooling?
Answer: Ice at 273 K would absorb latent heat as well as the heat heat energy in order to attain the room temperature. Therefore, ice at 273 K is more effective in cooling then water at the same temperature.
Why does a soft drink cool faster when surrounded?
Hence, (i) a bottle of soft drink cools faster when surrounded by ice cubes than by ice cold water because the soft drink loses an additional 336 J of heat energy for 1g of ice at ${0^ \circ }C$ than 1gm of ice-cold water at ${0^ \circ }C$. (ii) Material X has a higher specific heat capacity.
Which do you think would be more efficient for cooling a mass of cold air or a mass of cold water?
Cold water can remove heat more than 20 times faster than air. In effect, this means that a much larger volume of air is needed to achieve the same amount of cooling as a quantity of cold water.
What is the state of water at 0 C?
solid
> Water’s physical state at various temperatures like at 0°c: It would be ice in the form of solid at 0°c. It is the freezing point of water everyone knows. Similarly, at 25° c it would be water which is used for drinking, washing all would be this water and in liquid form.
Would you cool a bucket of water more quickly by?
The water can be cooled quicker by placing ice in it. If you place the bucket of water on ice, the ice will gain energy from the surrounding and melt. The ice melts by taking energy from the water present the in bucket. Here water is losing more energy so it becomes cooler faster.
Why do drinks taste better when ice melts?
The ice, being cooler than the drink, gets heat transferred to it from the drink (Newton’s law of cooling). (This continues after it melts, too.) The ice melts, and the cool liquid mixes with the drink, which makes the mixture feel cooler.
Why does ice melt faster in hot weather than cold?
Because of the high latent heat of fusion of ice i.e 334j/g.This means that one gram of absorbs 334joules of heat from the cold drinks to melt.Moreover when ice melts and forms water,it does the work of water It absorbs extra 4.2 joules of heat energy while cooling by 1 degree Celsius.
What happens when you put an Ice Cube in orange juice?
This would happen with water at zero degrees Celsius and a cup of orange juice, for instance. However, when you drop an ice cube at zero degrees Celsius into the same cup of orange juice, the new mixture’s intermediate temperature will be lower because ice melts.
What happens to ice when it cools the glass?
The cooling process actually happens in stages. Because ice floats, it cools the water near the top of the glass first. As the top layer of water cools, its density increases, causing it to sink to the bottom.
