Options:
A) Partly potential and partly kinetic
B) Totally kinetic
C) Totally potential
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
The exact value of internal energy is not known as it includes all type of energies of molecules constituting the given mass of matter such as translational, vibrational, rotational. The kinetic & potential energy of the nuclei & electron with in the individual molecules and the manner in which the molecule are linked together etc. $ E=E_{translational}+E_{rotational}+E_{vibrational} $ Thus, we can say that internal energy is partly potential and partly kinetic.
