Question:Which layer of the sun is only seen during the height of a total solar eclipse?
Answer: Corona
Explanation:During a total solar eclipse parts of the Sun that we normally can't see become visible but during it we can see the corona

Answer:
yeah the answer under the explanation
<em>Explanation:</em>
<em>The answer is (4) exothermic with ΔH = -1640 kJ. The 1640 kJ energy is at the right side of equation means that it releases energy. The enthalpy change means the energy of production minus the energy of reactants. If it is exothermic, the ΔH < 0.</em>
This is a common laboratory experiment called calorimetry which determines the specific heat capacity of the sample metal.
By the Conservation of Energy,
Energy of Metal = Energy of Water
mCmetalΔT = mCwaterΔT, wherein Cwater = 4.187 J/g·°C
(26.5 g)(Cmetal)(98 - 32.5°C) = (150 g)(4.187 J/g·°C)(32.5 - 20°C)
Solving for Cmetal,
<em>Cmetal = 4.523 J/g·°C</em>
The words that complete these descriptions are law, hypothesis, and experiment.
<h3>What is a law?</h3>
In science, a law is a statement that accurately describes the way a natural phenomenon occurs. Due to this, laws are created after testing a hypothesis several times. This matches Jean-Baptiste's proposal because his idea about heat flow has been tested by himself and others multiple times.
<h3>What is a hypothesis?</h3>
Different from a law, a hypothesis only states a possible explanation but this should be tested to become a law. This concept can be applied to Sadi because he only has an idea about heat flow but this has not been tested.
<h3>What is an experiment?</h3>
This is a procedure that aims at testing a hypothesis. This concept applies to James because he is carrying out an objective procedure to understand energy and heat.
