Azam had a metal pencil box and a wooden block on his table. When he touched them, the pencil box felt colder compared to the wooden block. When he measured their temperatures using a thermometer, he found that both the objects were at the same temperatures.
What could be the reason for Azam to 'feel' that the pencil box was cooler?
a) Air around the pencil box was at a lower temperature which made the pencil box colder.
b) Wood produces heat and so, must have been at a higher temperature than the pencil box.
c) As metal is a better conductor of heat, it drew away heat from his hand faster than the wooden block.
d) Metals are always at a lower temperature than other substances and so, there has been an error in measurement.
