False

3

Which of the following statements is false?

Answer 1

An an object emits less radiation than it absorbs, the temperature will decrease.

Step-by-step explanation:

The objects emit and absorb radiation, when it is balanced, both the temperature and the radiation are equal but when they vary both change in the same way.
