Question

Give reasons for the following:
(1)
In summer marble floor inside the house appears cooler than wooden floor.
(ti)
Steam at 100
causes more severe burns on human body than water at 100C​

Answer 1

Answer:

1)Marble as a Heat Conductor

The reason that marble feels cold is because it conducts heat differently than other surfaces. ... When you stand on wood flooring or carpet, the fibers and tiny air pockets within those materials heat up, but they do not dissipate quickly as does on marble.

2)Steam will produce more severe burns than boiling water because steam has more heat energy than water due to its latent heat of vaporisation. Steam and boiling water can exist at varying temperatures but it is only correct to assume here that both are at the same temperature.
