Two otherwise identical objects have temperatures of 1000 K and 1200 K, respectively. The object at 1200 K emits roughly twice as much radiation as the object at 1000 K. (T/F)

True

The object with the temperature at 1200K emits twice as much radiation as the object at 1000K.

Explanation:

The Stefan-Boltzmann law establishes how much an object radiates as a consequence of its temperature.

  (1)

Where is the radiant power, is the Stefan-Boltzmann constant and T the temperature.

Case for the object with :

Case for the object with :

Hence, the object with the temperature at 1200K emits twice as much radiation as the object at 1000K.
