Substances can emit or absorb radiant energy to varying extent provided their temperature is above ____
Show Hint
All real objects emit radiation if \( T>0\,K \).
Updated On: June 02, 2025
- 273\(^\circ\)K
- 298\(^\circ\)K
- 0\(^\circ\)K
- 1000\(^\circ\)K
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Any object with temperature>0 K emits radiation.
At absolute zero (0 K), thermal motion ceases and hence radiation emission stops.
At absolute zero (0 K), thermal motion ceases and hence radiation emission stops.
