Which of the followings are true or false. a. The total internal energy ( E ) of a chemical system equals the sum of the kinetic and potential energies of all the particles in the system.
1. True
2. False

b. The sum of all the energies due to the motions of the particles in a system is a form of specifically called thermal energy.
1. True
2. False
c. The energy in a chemical system that results primarily from the arrangement of the nuclei and electrons within an atom or compound is a form of specifically called Changes in the internal energy of a system take place when energy is transferred as work, or both.
1. True
2. False

When a chemical reaction produces a gas, the newly formed gas pushes away the atmosphere and creates space for itself such that the system loses energy as:

A. True

B. True

2. It losses energy as heat.

Explanation:

Internal energy is the sum of the potential and kinetic energy of all the particles in the system that form the system.

2. Atoms in a chemical system consist of nucleus which are positively charge and the electrons surrond it which are negatively charged. The protons are positively charged and the neutrons are neutral and this require energy to move, a change in the internal energy convert it to work.

Statement that there is equality between internal energy ( E ) of a chemical system as well as sum of the kinetic and potential energies is True.

Statement that the summation of all the energies in the system is regarded as Thermal energy as a result of motion is True.

The statement that energy in a chemical system is formed due to arrangement of the nuclei and electrons within an atom is True.

When a gas is produced from chemical reaction , the newly produced gas will create a space for itself by pushing atmosphere a way and energy will be lose as Heat.

The internal energy of a thermodynamic system can be regarded as energy that is found within the system.The thermal energy serve as the overall energies as a result of motion in the system

It can be concluded that the energy in chemical system can be occur as a result of arrangement of the nuclei and electrons within an atom

When Earth's tectonic plates grind past one another, enormous amounts of energy can be released in the form of earthquakes. Volcanoes are also often found near plate boundaries because molten rock from deep within Earth called magma can travel upward at these intersections between plates.
