Question

a brass tumbler feels much cooler than a wooden tray on a chilly day give reason

Answer 1

Answer:

Brass is a thin plate or sheet of metal while wood is a thicker lodge. Therefore, wood has a large surface area and traps more heat in it due to high absorptivity. It has low thermal diffusivity so heat flows out of it slowly when the surrounding is in the chilled state.

In contrast, brass has high reflectivity and low absorptivity due to a small area. In cold weather, the temperature of every object falls down. Therefore, heat goes out of brass more rapidly due to low absorptivity than wood. Brass can not hold heat inside it for a long time and gives it to the surrounding.

Thus when we touch brass heat escapes toward the object due to conduction and we feel it much cooler.
