When a warm beverage meets ice, heat flows from the liquid to the colder solid until thermal equilibrium is reached. This exchange is governed by the principle of conservation of energy: the heat lost by the drink equals the heat gained by the ice as it warms, melts, and then warms further as liquid.
The calculation hinges on three thermal processes: (1) the sensible heating of the ice from its storage temperature to 0β―Β°C, (2) the latent heat absorbed during the phase change from solid to liquid, and (3) the sensible heating of the resulting melt water from 0β―Β°C to the final drink temperature. By summing these contributions we can solve for the mass of ice required.
In practice, the result guides bartenders and home entertainers in preparing perfectly chilled drinks without overβdilution. Adjusting variables such as the initial drink temperature, desired final temperature, or the temperature of the ice stock lets you fineβtune the amount of ice for any scenario.
