Does keeping a metal spoon in hot coffee help it cool faster?

The metal spoon is a good conductor of heat. It also has a handle that protrudes out, with a fair amount of surface area to radiate heat out, and the spoon will also cool by convection. This definitely will cool the coffee down faster.

Scientists at the Massachusetts Institute of Technology (MIT) did a scientific study on this years ago.\n\nThe rate of loss of heat from a liquid is a function of the starting temperature to the 4th power (T^4).  So, if you want your coffee to stay warmer longer, add the milk immediately.  It immediately reduces the initial temperature.

Depends on the thermoconductive properties of a certain material. Copper for example will heat up or cool down very fast.

Yes.  You can form a supersaturated solution with salt and boiling hot water in a glass jar.  Tie a pencil to one end of a string and a paperclip to the other.  Allow the pencil to rest on the top of the jar so the paperclip can hang in the solution, almost touching the bottom of the jar.  Allow the jar to sit undisturbed and you'll see crystals forming within 24 hours.

It depends on the structure of the sentence. You can ask someone if they would like a cup of hot coffee and say that you are going to make some coffee hot by warming it up. or "I am going to warm up this coffee and make this coffee hot and then I will drink my hot coffee." Hope this makes sense to you.

I think u have to use white vinegar, it cleans the coffee pot so why not the thermos but I would wash it out after the vinegar, good luck hope that helps :o)!

It depends on the temperature of the cream and the coffee. If the coffee was piping hot and the cream ice cold then the cream would have an impact on the overall temperature. If the cream was room temperature and the coffee piping hot the cream would have a negligible impact on the coffee. If the coffee and the cream were both the same temperature the coffee would stay the same temperature. In either case it depends on the temperature of the cream and the amount of cream you are adding to the coffee, but in most cases you would not notice the drop in temperature.

Its a balloon of glass, shaped (usually) to be like a bottle. But unlike a balloon, the volume inside the glass has had all the air extracted before it was sealed (thus forming an airless environment known as a vacuum). \n\nIf there is no air in the space between the layers of glass there are no molecules present. Molecules are required to transfer heat. So if you put your hot soup in a vacuum flask it stays hot for a long time because the heat cannot escape. If you fill it with cold beer, the beer stays cold because the warmer air outside can't get in.\n\nSimple but effective.

No... don't drink hot water... it can really hurt you than help.\nDrink cold water instead... you'll body will burn additional calories warming the water internally after you've drank it.

Supposedly, a silver spoon will help preserves the bubbles in a champagne bottle, but it's bunk.  It actually makes the bubble go away quicker because it gives them a condensation site.  See the below for more:

when milk sits out on the counter for every 15 minutes you lose one day on the date on the container. milk is not dangerous warm, because when you warm it you are warming it faster than leaving it at room temp. and it is not going to sour if you use it right away.
