The article explains how adding cream to hot black coffee can keep it warmer for a longer period. This phenomenon occurs due to three primary factors: cream lightens the coffee's color, reducing its heat loss; it increases the coffee's viscosity, slowing down evaporation; and by initially cooling the coffee, it slows heat radiation according to the Stefan-Boltzmann Law. Understanding these properties can enhance your coffee experience, encouraging experimentation with different creamers to find the perfect balance between flavor and warmth.
Adding cream to black coffee can prolong its heat retention, as it reduces the coffee's darkness, increases viscosity, and slightly lowers its initial temperature.
The darker the coffee, the quicker it radiates heat. Cream lightens the coffee, slowing down this process, leading to a longer retention of warmth.
Fat in cream adds viscosity to coffee, which reduces the rate of evaporation, thereby allowing the coffee to stay hotter for an extended period.
The Stefan-Boltzmann Law highlights that a cooler temperature will radiate heat slower, explaining why cream keeps your coffee hot for longer.
