A) its molecular kinetic energy increases
B) molecular potential energy decreases and molecular kinetic energy also decreases, total energy remaining constant
C) molecular potential energy increases and molecular kinetic energy decreases; total energy remaining constant
D) its molecular potential energy increases
Correct Answer: A
Solution :
The gas molecules keep on colliding among themselves as well as with the walls of containing vessel. As the temperature rises molecules gain energy and their velocity increases with rise in temperature, speed of molecule increases as \[v\propto \sqrt{T}\]
