The correct answer from the choices is: D
Resonance is an event where an external force or vibration moves another system to oscillate with higher amplitude at certain frequences or there is a transfer of energy between two or more different storage modes.
Answer:
ocean heats up and cools down relatively slowly. Therefore, areas near the ocean generally stay cooler

Answer:
C) Reactants absorb a minimum amount of energy and then release a smaller
amount of energy as products form.
Explanation:
The statement that best describes how to read a reaction pathway from the graph of an endothermic reaction is that, reactants absorb a minimum amount of energy and then release a smaller amount of energy as products form.
In an endothermic change, heat is absorbed from the surrounding.
- As such, the surrounding becomes colder at the end of the reaction.
- On a graph of an endothermic reaction, the reactants absorbs a minimum energy.
- As the reaction proceeds, the products gives off an even lesser amount of energy.
Volume of Argon = 59.972 L
<h3>Further explanation</h3>
In general, the gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08206 L.atm / mol K
T = temperature, Kelvin
At STP(0 C, 1 atm), 1 mol gas= 22.4 L
so for 20 L
For Argon
P = 1 atm
T = 273 K x 3 =819 K (tripled)
n = 0.893 (the same number of moles)
R = 0.082 L/atm.mol K
