The answer is A. Friction
hope this helps :)
D is the correct answer!!
Answer:
221.17 kJ
Explanation: Note the heat of vaporization is in kJ/mol,then to determine the number of moles of water: divide the mass by 18. Then multiply the number of moles by the molar heat of vaporization of water.
N = 97.6 ÷ 18
Q=molar heat *moles
Q = (40.79) * (97.6 ÷ 18)
This is approximately 221.17 kJ
The ionosphere is the part of the sun-layers which allows us to see the northern lights or auroras. The ionosphere is the most concentrated with ions and charged electrons and reflects radio waves.
