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.
What travel faster heat or cold?
Heat travels faster than cold. This is because heat is the transfer of energy from a warmer object to a cooler one, which occurs through molecular collisions. Cold, on the other hand, is simply the absence of heat energy.
If you stick a metal rod in snowbank. the end in your hand soon becomes cold. Does cold flow the snow to your hand?
No, cold does not flow from the snow to your hand. When you touch the metal rod, heat from your hand is transferred to the metal, which conducts heat away from your hand into the colder snow. Your hand begins to feel cold as it loses heat.
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?
When a cold object is touched, heat energy flows from the person's hand to the object. This is because heat always flows from the higher temperature (hand) to the lower temperature (object) in order to reach equilibrium. The sensation of coldness is due to the loss of heat energy from the hand to the colder object.
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 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.
Explain why does a soda can feel cold in your hand when you take it out of the refrigerator?
When you take a soda can out of the refrigerator, it feels cold because it's at a lower temperature than your hand. As the can's surface comes in contact with your warmer skin, heat from your hand is transferred to the can through conduction, making it feel cold to the touch.
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).
Is cold the opposite of thermal energy?
No. It's the absence of thermal energy.Similar to the situation where 'dark' is not a substance that you can generate, orhold in your hand, or put in a bottle. It's the absenceof something, called 'light'.Answer'Cold' is the opposite to 'hot', and describes temperature, not energy.
What is the difference of surface wave and body waves?
Surface waves travel along the Earth's surface, causing most of the destruction during an earthquake. Body waves, on the other hand, travel through the Earth's interior. Body waves include primary (P-waves) and secondary (S-waves) waves, which are faster than surface waves.
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.
