Water is evaporated, an edothermic process; also heat is lost by conduction, radiation, convection.
Tea in a metal cup would cool down relatively quickly, since the metal cup wall conducts heat very well.
Ofcourse it will cool down! the cup of hot chocolate isn't enough to heat the room, but the room is big enough and can cool down the cup. It's like putting an icecube in an oven. The icecube won't freeze the oven; the oven will melt the icecube.At 25 degrees the cup of hot chocolate will eventually freeze!!!!!
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.
1 cup
It does. Any object will heat up (or cool down) to the ambient temperature.
you will need: the liquid a cup a scale first: way the cup then jot the weight down secondly: pore the liquid into the cup thirdly: it and then jot it down forthly: take away the weight of the cup from the cup and the liquid and you have the weight of the liquid

Depends on: * mass or volume of solvent * type of salt * type of solvent * heat input * agitation of solvent
If the mug is made of glass, it will allow the water to cool faster. A thick styrofoam cup is better than a paper cup, even though the insulating properties of the materials are similar.
because the interracial porportions in the cup are virtually stronger in the cup, but the saucer has more optical durability, so the coffe sees the saucer and goes, "dang that saucer be pim ping" but it is too much for the coffe to handle, therefor the coffee cools down quicker than in the cup
