Sodium chloride is the most common substance. Besides it, magnesium chloride and calcium chloride are also dissolved in seawater. Seawater consists of a large number of gases also such as oxygen, nitrogen, carbon dioxide, etc.

i think the correct answer from the choices listed above is option c. when the kinetic energy of particles in a liquid state decreases

explanation:

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
