Cold doesn't travel, heat does. The heat travels from your hands to the snow.
No the heat flows out of your hand. Cold can never enter. the reason you get cold is because heat leaves not cold entering.
Metal expands from heat and contracts in cold

Potassium metal is a metal that explodes when put in cold water. It causes a chemical reaction which results in a large explosion.
The extent of cold work that a metal can withstand depends on the recrystallization point which is usually carried out at room temperature. The cold rolling and cold drawing of metal significantly improves surface finish.
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
Stick it in cold water.
Normally, any spoon you put in ice cream(wooden or metal) becomes cold.

No it won't. Try warming and drying the metal with a hairdryer or heat gun first.
Cold metal.
Various linkages in a car can "stick" in cold weather when the grease or other lubricant becomes cold. This applies to locks, accelerator linkages, etc. You can often solve the problem by dissolving the old lube with brake or carb cleaner. There is no need to oil the linkage.
In hot metals the kinetic energy of electrons becomes higher and they move randomly so their movement in one direction becomes decreased so the conductance becomes decreased.

Chap stick won't cure a cold sore.
Your body is mostly made of water. When you touch a very cold object, for example ice or metal, it freezes the water in your fingers and the object together. This can only happen with anything with a little bit of moisture on it: ice does not stick to dry objects, as there is no water there to freeze. -- Cucarach1 its not :/
