it is the conduction
You leave a hammer in the sun for several hours when you pick it up heat is transfered to your hand?
the particles in the hammer transfer heat to the particles in your hand through direct contact.
If air is considered as a poor conductor of heat why is it then you have to use insulator in handling hot materials?
When you pick up a hot item there is no air to insulate your hand.
How do you move things with your hand?
just pick it up.
What is a pick that miners use?
geologists hammer or rock pick if your thinking about hand samples. A giant hydraulic hammer on a drilling platform if your mining.

convection
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.

What is the thing you use for the guitar in your hands?
If you mean what you hold in your hand to strike or pluck the guitar strings, it is a plectrum, more commonly called a flat pick or just pick.
What keeps drinks colder glass or aluminum?
Glass because it is a poor conductor of heat. Aluminum is highly conductive, which means that when you pick it up the heat from your hand would move quickly through the aluminum and into your drink.
How do slaves pick cotton?
