I guess it is the second one but you missed the state symbols.
Answer and
Explanation
I believe the correct answer would be the last option. When an electrons moves from an excited state to the ground state, it would release energy. An electron in the excited state would mean that it contains high kinetic energy so to move to a lower state some of these energy should be released.
Vacuoles are storage bubbles found in cells. They are found in both animal and plant cells but are much larger in plant cells. Vacuoles might store food or any variety of nutrients a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination.
Answer:
Average kinetic energy of gases, which is derived from the RMS (root mean square speed) and KE equation, can be solved as:
It appears that the average KE of gases is dependent on the temperature which means that all gases will have the same KE as long the temperature is the same
