Answer:
Heat energy.
Explanation:
The exited electron releases the absorbed energy as heat energy that provides energy to electrons to move from one orbit to another orbit. The electron avails kinetic energy which provides motion in the electron when the energy is absorbed by the electron while on the other hand, electron releases energy which brings the electron into its original orbit. So we can say that the electrons releases energy in the form of heat and come back to its original place.
The answer is (3) 566 K. For this problem, you need the combined gas law, which is P1V1/T1 = P2V2/T2 (variables represent Pressure, Volume, and Temperature). You are looking for T2, so you get T2 = P2V2T1/P1V1 = (38.7)(1880)(273)/(79.0)(444) = 566 K.
Elements are composed of tiny particles called atoms. Atoms of any one element are different from those of any other element. Atoms of different elements can form compounds by combining in whole-number ratios. Chemical reactions occur when atoms are separated, joined, rearranged.
Answer:
A. A cube that measures one cm3 on each side
Explanation:
hope this helped :)
A young river has very few tributaries and flows quickly. It's channels erode deeper rather than water. So, the answer is A.
Hope I helped!
