The milk froth is white and contains lots of air bubbles. Suggest why the Cappuccino coffee cools down more slowly than the Americano coffee.

Asked by cassiesalter2

Answer (3)

Cappuccino coffee cools down slower because the air bubbles at the top of the drink act as an insulator which slows down the rate at which thermal energy is transferred to the surrounding air.

What is thermal insulation ?
The reduction of heat transfer between objects in thermal contact or within the range of radiative influence is referred to as **thermal insulation. **Thermal insulation can be achieved through the use of specially designed methods or processes, as well as appropriate object shapes and materials .
Heat flow is an unavoidable result of contacting objects of different temperatures. Thermal insulation is a region of insulation in which thermal conduction is reduced, forming a thermal break or barrier, or thermal radiation is reflected rather than absorbed by th e lower-temperature body.

A cappuccino cools down more slowly than an Americano due to the insulating properties of the milk froth, which contains many air bubbles. These air bubbles slow the thermal energy transfer to the surrounding environment, keeping the cappuccino hotter. In contrast, the Americano lacks this insulating layer, leading to faster cooling.
