Tray
You can probably paint a plastic serving tray and hang it on a wall as a decoration. You can probably also use a plastic serving tray as a paint palette.
A tray can be made from plastic, wood, stainless steel, aluminium, etc. A tray is handy to carry food on, or to have on your knees while eating a plate of food while watching the TV.

Weeping is when liquid flows downward through the holes in a distillation tray. Normally vapor rises up through the holes and contacts the liquid on the tray. If the vapor rate is too low the liquid may be able to drop to the next stage through the holes, resulting in less than optimal vapor/liquid contact (and therefore less than optimal separation). Condensed liquid from above trays is generally distributed onto a distillation tray via a weir.
the metal that is used is collective jasgarter in most stamper trays
you will not get burn because it is open. hot metal will attract cold air and throw it away when its hot. but if its close your hands well be cook.
if the tray is metal. i think it could be tried.
Simple, Get a bin bag, metal tray and plastacine. put the metal tray on the bin bag and put the plastacine in the middle of the tray grab the plastacine and shuffle the metal tray about the get a coin and touch it with coin
a tray
The answer is D. The metal ice-cube tray has a higher conductivity.
The metal tray has both a higher specific heat (ability to gain or hold heat) and a higher conductivity (ability to transfer heat). So while the ice cream will increase in temperature where you touch it (and hence only absorb a small amount of body heat), the tray can absorb more heat, and transfer it to all of the metal and ice in the tray. (This is also why you can lick a wooden pole in the winter, but not a metal one!)

because metal is a good conductor of heat therefore it keeps your food warm, but you don't want it to burn you when you move it or do anything so they put it on a wooden tray because wood is a poor conductors of heat
Ya... have you noticed that if you touch a plastic tray this does not happen. They are both the same temperature but because metal is a good conductor of heat when you touch the metal tray it removes heat from your skin so fast that it actually creates a very thin film of ice between the surface of the tray and the moisture in your skin. This acts like a cement until it either thaws or you use enough force to break the bond
separate the pieces and put them on an unheated metal tray
This is a matter of melting and freezing. When you touch the tray, the warmth from your finger quickly melts a bit of a ice and creates a thin layer of water between the tray and your finger. Since the tray is so cold, it quickly freezes that thing layer of water forming an icy bond between your finger and the tray.
