A reaction that gives off heat energy is called Exothermic. (Answer).

A reaction that absorbs heat from the surroundings is called endothermic.

Answer: Exothermic

Explanation:

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and \Delta H for the reaction comes out to be negative.

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and \Delta H for the reaction comes out to be positive.

HCl(aq)+NaOH(aq)\rightarrow KCl(aq)+H_2O(aq) is an example of neutralization as acid and base combines to form salt and water and exothermic reaction as it releases heat in the reaction.

Levart [38]

B) convection

Explanation:

Once the sun's energy reaches the earth's atmosphere by radiation, it is circulated within the atmosphere and oceans through convection.

The energy of the sun on earth is moved between the ocean and the atmosphere by air around us.

  • Heat transfer in fluids is by convection.
  • It involves the actual motion of the particles of medium from one place to another due to differences in temperature and density.
  • Air close to the surface of the ocean is less dense and hot due to high temperature.
  • The air rises and it is replaced by colder air masses.
  • This exchange leads to the development of convective cells.
  • This moves the energy of the sun between the atmosphere and the ocean surface.
