Answer:
B
Explanation:
Atom consists of proton and neutron in center (often referred as nucleus) and electrons circling those things.
It is quite easy:
1 cal = 4,1868 J
Solution is:
2930 kcal = 4,1868 * 2930 [kJ] = 12267,324 [kJ]
The answer should be its kinetic energy increases.
The kinetic energy of a particle means how fast they move, the faster they move, the more kenetic energy they have. In addition, when it moves faster and have more kenetic energy, their temperature becomes higher too.
Therefore, the answer is the first one.
