Energy travels from your hand to the cold surface. Cold is merely the relative absence of heat.

When you touch a cold surface does cold travel from the surface to your hand or does energy travel from your hand to the cold surface?
Energy travels from your hand to the surface, because even the slightest touch transfers energy. Cold doesn't transfer from the surface to your hand, your nerves just tell your brain that the surface is cold.
If you stick a metal rod in snowbank. the end in your hand soon becomes cold. Does cold flow the snow to your hand?
Cold doesn't travel, heat does. The heat travels from your hands to the snow.
When Javier touches a hot mug of tea energy is transferred from the surface of the mug to his hand. What kind of energy is this?
The transfer of heat from cup to hand is known as conduction.
Why would your hand feel cold if you wet the back of your hand and blow on it?
Your breath evaporates the moisture which cools the surface temperature of the skin.
when a cold object is touched state whether the heat energy flows from the person's hand to the object or the object to the person's hand and why is it so?
Heat always flows from hot to cold. Cold is the absence of heat.
Why is a shadow made?
Light travels in form of Electro Magnetic waves. EM waves, carry their energy in small packets of energy named Photon. (imagine small pieces of water baloons are hitting a surface and splashing their water on e surface) that's how light is transmitted, and you can see its reflection. Now imagine that you out ur hand on top of that surface, instead of the surface your hand will get wet. In scientific terms, your hand is absorbing the energy, and blocking its transmission path. So the surface will be left ( according to our analogy, surface will remain dry) untouched with the photons, that's why it will be dark.
When you touch a cold object state whether heat energy flows from the object to your Hand or from your hand to the object?
Heat has the natural tendency to flow from a warmer to a colder object. If your hand is warmer than the "cold object", then heat will flow from your hand to that object.
Heat let us feel hot or clod?
heat is actually a form of energy and should not be confused with temperature. if something feels hot that means the thing you touched is hotter than you, and that as a result energy from that thing is flowing into your hand; if your hand is hotter than the thing, then it will actually feel cold to you, as energy flows out of your hand into that thing. So, the flow of heat can make us feel either hot or cold, depending on which way the energy flows (into or out of our bodies).
Why does an endothermic reaction feel cold if energy is being absorbed?
Because the energy(heat) is being pulled out of your hand. Heat transfer from the hottest substance to the coldest
Stars are different from planents because they?
Because they emit energy themselves due to various chemical reactions on their surface or core. Planets, on other hand reflect the energy from the stars.
What energy transformation took place in the strumming a guitar?
the energy that has transformed in a guitar when you strummed is sound energy,besides it makes a sound when you strummed a guitar ..
What occurs when is transferred from one object to another?
Well, it's exactly that- energy is being either radiated, convected, or conducted through, to, or from an object. Energy needs a medium to travel through- and it's travelling because it needs to reach what every little atom in the world needs- equillibrium. For example, the reason things feel hot and cold is because energy is being transfered from the- let's say, an ice cube- to your hand. The cold energy is trying to mix with the hot energy, and create what we bluntly call room temperature (one side effect, though, is a melted ice-cube.) xD
