Temperature of hot cup of tea?
The best cop of tea is served at 115 degrees F. Many other kinds of teas need a different temperature. White and green tea is best served at 100 F.
This question may arise as water often cools to point below the temperature of the room it is sitting in. In this case the amount of water in a cup of tea is sufficiently small that the heat content will reduce to its stable point over the course of an hour.The exact temperature depends on: the temperature of the room it is in the surface area exposed to the air in the room the rate…
because the tea is very hot. the boiling point the water is 100degree and above this ,250degrees,is the gaseous state .in case of hot tea there are both things .tea is boiled as well as it has vapour .as we know that the boiling point of an object is lesser than the gaseous state that is why you blow air on a hot cup of tea
You can drink hot tea (or any hot beverage) faster from a saucer than from a cup because tea has a larger surface area exposed to the air when it is in a saucer. Because the saucer is wider and shallower than a cup, more of the tea is in contact with the air, so the heat in the liquid is able to dissipate into the atmosphere more quickly.
Possibly, if the pitcher was large enough. Heat and temperature mean two different representations of heat energy. Heat is the absolute value, temperature is the average value. For example, a swimming pool at 25 deg C has more heat contained within it than a cup of water at 25 deg C. However the swimming pool has the same temperature as the cup of water. Since heat is based on the absolute value, which is proportional…
It won't unless the other cup is colder than the tea. If you pour hot tea into a cold cup, the tea will give up heat to warm the cup. The same thing applies to cold beer in frosty mugs. The reverse applies when you pour boiling water into a thick mug to warm it up before you pour in the coffee so as not to cool the coffee.
