We perceive an object as hot or cold according to how fast its particles are moving. The faster they move, the hotter the object.
What term describes how hot or cold an object is?
Heat is transferred between a hot and a cold object by conduction through direct contact. When the hot object touches the cold object, kinetic energy from the hot object's particles is transferred to the cold object's particles, causing them to vibrate and increase in temperature until thermal equilibrium is reached.
Energy does not naturally transfer from a cold object to a hot object. Heat always flows from a hot object to a cold object in order to reach thermal equilibrium. This is described by the second law of thermodynamics.
When an object is heated, its particles gain energy and move faster, causing them to spread out and increase in size. On the other hand, when an object is cooled, its particles lose energy and move slower, causing them to contract and decrease in size. This effect on size is reversible and depends on the temperature change.
Heat always travels from a hot object to a cold object. This is based on the second law of thermodynamics, which states that heat naturally flows from regions of higher temperature to regions of lower temperature in an attempt to reach thermal equilibrium.

A cold object is usually more dense than a hot object because colder temperatures cause particles to move less and come closer together, increasing the object's density. Conversely, in a hot object, particles move faster and spread out, decreasing its density.
Thermal energy transfers from hot objects to cold objects through a process called conduction. This occurs when the particles in the hot object collide with the particles in the cold object, transferring energy and causing the cold object to heat up.
Because as your hands are warm and the object is slightly colder then it makes a big difference...
it is warm but wind makes it cold
