Answer:
2. Volcanoes
Explanation:
The interior of some planets (e.g earth) contains some hot flowing fluids called lava which has a very high thermal energy. The lava as a means of escaping the confinement within the planet, burst out by creating an opening through the ground to the surface of the planet to release the energy (lava).
This process in which the energy is released to the surface of the planet is termed volcanic eruptions. Which occurs majorly in some susceptible regions of the earth.
The openings in the ground that release energy from deep inside the planet is thus called volcanoes.
Answer:
-1043,8 KJ
Explanation:
Hello!
It is necessary to accommodate the reactions to get the reaction of my interest.
Reaction A reverses what modifies its energy in its sign (+72.6 KJ).
Reaction B doubles, which also doubles its energy (-514.4 KJ x 2).
Reaction C reverses what modifies its energy in its sign (-87.6 KJ).
By sum of the energies I get the energy of the global reaction.

Answer: Option (d) is the correct answer.
Explanation:
Endothermic process is a process in which energy or heat is absorbed by reactant species.
For example, melting of ice cubes is an endothermic process as it is absorbing heat from the surrounding and gives a cooling effect.
Thus, we can conclude that the process in which a substance gains energy is an endothermic process.
