The average temperature of a cup of coffee should be served between 160 degree Fahrenheit and 185 degrees Fahrenheit. The liquids in this temperature range can cause significant scald burns.
A hot cup of coffee will cool down at a certain rate, but as the coffee cools, the rate at which it cools slows down. This is why a "lukewarm" cup of coffee cools down so slowly. Even though the warm cup of coffee is cooling down quicker at first, the lukewarm cup essentially has a "head start" on the way to room temperature.
You can program the temperature to whatever you prefer.
you ask for a cup of hot coffee.
The hot cup of coffee has more thermal energy than an iceberg. This is because thermal energy is directly related to temperature, and the cup of coffee is at a much higher temperature than the iceberg, meaning it contains more thermal energy.
Metal absorbs and conducts heat better than the air or the ceramic cup.
When you stir a cup of coffee, the energy of the coffee is initially raised from the bottom of the cup. This can causeÊthat hot coffee to cool quicker, but it depends on the temperature of the cup and the coffee's surface.
Very hot
Yes, you can add hot water to coffee pods to make a quick and easy cup of coffee.
The hot cup loses heat faster, but only until it becomes a warm cup itself. Then it loses heat as the warm cup did at the beginning. However, by this point, the hot cup is warm, but the warm cup is now cooler too. Therefore, the warm cup will still become room temperature first.
Hot coffee is a solution, not a suspension. No matter how long you wait, the coffee does not settle out to the bottom of the cup.
Yes.
The situation was not that the coffee was too hot. What happened was that a woman had purchased a cup of hot coffee from a McDonald's. While she was driving, the coffee spilled into her lap and burned her. She sued McDonald's on the basis that the cup did not have a printed warning about the coffee being hot (such as CAUTION: CONTENTS HOT), and because it was true that the cup did not indeed have such a warning, she won the case.
