You leave a hammer in the sun for several hours when you pick it up heat is transfered to your hand?
The hammer absorbs heat from the sun, raising its temperature. When you pick it up, heat is transferred from the hotter hammer to your hand, which is at a lower temperature, causing your hand to feel warmer due to the heat transfer.
When you pick up a hot cupheat is transferred from the cup to your hand primarily by?
Conduction. Heat is transferred through direct contact between the hot cup and your hand, causing molecules to vibrate and pass on energy to your skin, resulting in the sensation of warmth.
If air is considered as a poor conductor of heat why is it then you have to use insulator in handling hot materials?
While air is a poor conductor of heat, it can still transfer heat through convection. Insulators help to minimize heat transfer by creating a barrier that reduces the flow of heat. This is important when handling hot materials to prevent burns or damage.
When you pick up a spoon your body heat will warm up the part of the spoon you are touching why does the metal spoon feel colder than the wooden one?
Metal is a better conductor of heat than wood, so it draws heat away from your hand quicker, making it feel colder. Wood is a poor conductor of heat, so it doesn't draw heat away as quickly, resulting in a warmer sensation when touched.
Why a piece of metal feels colder than wood kept in cold place?
Lets say room temp is 75 degrees. Your body temp is around 98 degrees. metal conducts heat very well so when you touch it all the heat is transferred to the metal whereas wood is more insulating and the heat from your finger leaves at a much slower rate. Also, there is also a difference in emissivity between the two materials. They radiate energy differently. The metal object not only feels colder in the room (or hotter in the sun), it really is a different temperature. Wiki/Google "emissivity." Metal is a thermal conductor and Wood is a thermal insulator. When you touch the metal, the energy transfers rapidly to the metal, making it colder. When you touch the wood, the energy transfers very slowly from your hand to the wood.

How heat transfered by convection?
Convection is the process by which heat is transferred by a "fluid" (which, in this case, can actually mean a liquid or a moving gas - both are considered "fluids"). Heat is always transferred from an area of high heat to an area of low heat, regardless of the method. When your hand touches a hot stove, heat moves from the stove to your hand to try to "even out" the amount of heat between the two objects. In convection, heat is first transferred from an area of high heat to the fluid, then from the fluid to an area of (relatively) lower heat. Imagine you're sitting downwind of a bonfire. The wood has lots of heat - some of it is transferred to the air. The air is pushed toward you by wind, and when the air hits your skin, there is another heat transfer because your skin has less heat than the air. The net result is a transfer of heat from the wood to your skin, and we say this is by convection. Another example might be the way everything in a small kitchen gets warm in a hurry when things are baking in a hot oven. Some radiation occurs, but lots of air picks up heat from the stove, and then rises to be displaced by cooler air. The hot air heats things in the upper regions of the kitchen, and then cools and sinks. It then may return to the stove to pick up more heat as hot air there continues to circulate upward. Convection currents in air transfer heat.
Why solids pick up heat fast as compared to air?
Heat transfer takes place due to collision in atoms (of which everything around us is mad). In solids these atoms are near to each other but in gas atoms are very very far from each other. So in case of solids, it is easier to transfer the heat in form of collisions but in air it is difficult to transfer these collisions. Note: Heat is transferred in form of collisions because heat increases speed of atoms. This speed when transferred to adjacent atoms by collisions, transfers the heat.
