Q43 / 56 · NEST (NISER) 2011 · Physics

A solid aluminium cube of side 0.1 m is heated for 2 minutes in a furnace at temperature 1000 K such that the cube's temperature increases by 5 K . A larger aluminium cube of side 0.2 m is put in the furnace at temperature 2000 K for 1 minute. Assuming that the furnace behaves like a blackbody, the increase in temperature of the larger cube will be

A
2.5 K.
Correct answer
B
5 K.
C
10 K.
D
20 K.

Hence, the correct answer is option: 'B'.
