Question

why are some objects hot while aome are cold? class 7​

Answer 1

Answer:

In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects.

Answer 2

Answer:

Too hot to touch, too cold to scald. Objects feel warm or cold because of the rate and direction at which heat flows between them and our fingers. That, in turn, depends on the thermal conductivity of the material they're made of. Plastic's thermal conductivity is around 10 times lower than ceramic's.
