Place the steps involved in burning coal to create electricity in the correct order.
butalik [34]

Answer and Explanation:

  1. Coal is burned: Electrical Centrals burn coal with which they get enough heat. The coal might be pulverized to increase the effective combustion area.
  2. Water boils, creating steam. The heat generated by the burning coal is used to create water vapor that rises and moves turbines. This occurs when water passing through some tubes is heated by the hot gases coming from the burning coal, turning it into high-pressure steam.
  3. Moving steam turns turbines. The high-pressure steam is taken to turbines where it expands and moves the rotor which is the moving part of the turbines.
  4. Turbines generate electrical energy. The turbines are connected to a generator that transforms the energy produced by the rotor into electricity.

elena-14-01-66 [18.8K]

Answer:

The parietal layer of the serous pericardium is also known as the epicardium of the heart wall.

Explanation:

The pericardium is a sac composed of two layers which surround the pericardial cavity. The two layers of the pericardium are the fibrous and serous pericardium and the serous pericardium is further divided into two layers: the visceral and the parietal layers.

The fibrous pericardium is composed of the thick connective tissue and thus prevents overfilling of the ventricles.

The parietal pericardium lines the internal surface whereas the "visceral pericardium layer" is the innermost layer and is known as the epicardium of the heart wall.

Thus, the selected option is correct.
