AnswerIce at 273K (or 0° C) is solid while water at 273K (or 0° C) is a liquid. When both the substances, at 273K, are used for cooling, ice is more effective than water. This is because ice is a solid when it absorbs heat, it is used for two things
Whereas on the other hand, water is a liquid, when it absorbs heat it is used
Thus, we can conclude that ice at 0°C / 273K consumes more heat than water at 0°C / 273K. Hence, ice at 273 K is more effective in cooling than water at the same temperature. So, to summarise

Buy NowAnswer  Hint: To answer this question, you must recall the concept of latent heat. Water converts from ice to water absorbing heat. So, more energy is stored in ice than in water at the same temperature. Complete step by step answer: - The heat that is required to convert one state of a substance to the other without the change in temperature is known as latent heat. In other words, it is the energy required to convert a substance from solid state to liquid state or from liquid state to vapour state keeping the temperature constant. - The heat required to convert a substance in solid phase to liquid at constant temperature and pressure is known as latent heat of fusion. Similarly, the heat required to convert a substance in liquid phase to vapours at constant temperature and pressure is known as latent heat of vaporization. - At 273 K, ice absorbs more heat than water from the substance to overcome the latent heat of fusion and thus providing a more effective cooling effect. Water however does not absorb any extra heat from the substance.Thus, ice is more effective in cooling than water at 273 Kelvin. Note: When a substance absorbs heat from its surroundings, due to the loss of the heat in the surroundings, a cooling effect is observed. Not only melting of ice, but evaporation causes cooling as well. It is the process of conversion of a liquid to vapour at room temperature. It is different from vaporization as it occurs at room temperature while the latter occurs at the boiling point. When evaporating, the liquid absorbs heat from its surroundings thus causing a cooling effect.Answer: To achieve room temperature, the ice at 273 K will absorb latent heat as well as thermal energy. Water at a temperature of 273 K would just absorb heat energy to achieve room temperature. Thus, water at 273 K will absorb less environmental heat energy than ice at 273 K. Therefore, ice at 273 K is more effective in cooling than water at the same temperature. Additional information Latent heatLatent heat is defined as the heat or energy that is absorbed or released during a phase change of a substance. It could either be from a gas to a liquid or liquid to solid and vice versa. Latent heat is related to a heat property called enthalpy. Types of Latent Heat TransferLets us discuss some different types of latent heat that can occur. Latent Heat of FusionLatent heat of fusion is the heat consumed or discharged when matter melts, changing stage from solid to fluid-structure at a consistent temperature. Latent Heat of VaporizationLatent heat of vaporization is the heat consumed or discharged when matter disintegrates, changing state from fluid to gas state at a consistent temperature. Specific Latent HeatSpecific latent heat is characterized as the measure of heat energy (heat, Q) that is consumed or discharged when a body experiences a steady temperature process. Related articles
