You hold a metal object.Explain using your knowledge of physics whether the cold flows from the ice to your hand?
Because metals are strong thermal conductors, they feel colder or hotter to the touch than other materials at the same temperature. This implies they can quickly transfer or absorb heat from cooler or warmer items. Your skin can only feel its own temperature and cannot detect the temperature of other items. When you contact a piece of metal that is colder than your hand, your fingers swiftly lose heat and feel chilly, but when you touch metal that is hotter than your hand, your fingers rapidly gain heat and feel warm. Plastic and wood are good thermal insulators, but they don't transmit heat well.
Some metals may also heat up more quickly than other materials. Metals have a low specific heat capacity, which is a measurement of how much energy is required to increase a material's temperature by one degree. In comparison to a material having a bigger heat capacity, a material with a lesser heat capacity will achieve a higher temperature when the same amount of energy is supplied. The heat capacity of polyethylene, a popular plastic, is more than double that of most metals. Water has a significant heat capacity as well.
