![]() ![]() If the ice cubes are added to the beverage, they first heat up to the melting temperature of 0 ☌. Ice cubes from the freezer usually have a temperature of about -20 ☌. Heating the ice cubes to melting temperatureįigure: Dividing the cooling process into three steps (heating, melting and mixing)įor all those who do not want to deal with the derivation of the formulas, the final temperature can be calculated directly using the following Excel spreadsheet:Ĭooling drinks with ice cubes Download Heating the ice cubes to melting temperature.The entire cooling process can basically be divided into three steps, which will be discussed in more detail below: ![]() In reality, the surroundings and the glass are also involved in the heat transfer that takes place, but this is neglected in the following. ![]() For simplicity, it is assumed that heat is only transferred between the beverage and the ice cubes. In order to answer this question, it will first be shown how the final temperature after complete melting of the ice cubes and mixing with the beverage can be calculated. So wouldn’t it make sense to develop ice cubes that don’t melt? Or couldn’t one simply use copper cubes cooled in the freezer? Figure: Soft drink cooling with ice cubes The disadvantage, however, is that soft drinks are usually verwässern by the melting of the ice cubes. If you want to cool a warm drink relatively quickly in summer, you usually use ice cubes. Introduction (Excel spreadsheet for calculation)
