What is exchanged between the system and the surroundings ​

Chemistry
1 answer:
BartSMP [9]3 years ago
8 0

Answer:

see note under explanation

Explanation:

When describing system and surroundings the system is typically defined as the 'object of interest' being studied and surroundings 'everything else'. In thermodynamics heat flow is typically defined as endothermic or exothermic. However, one should realize that the terms endothermic and exothermic are in reference to the 'system' or object of interest being studied. For example if heat is transferred from a warm object to a cooler object it is imperative that the system be defined 1st. So, with that, assume the system is a warm metal cylinder being added into cooler water. When describing heat flow then the process is exothermic with respect to the metal cylinder (the system) but endothermic to the water and surroundings (everything else).

Answer:

Energy is transferred from one object to another when a reaction takes place.

Explanation:

Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few.  

The answer could be It is a well known fact that energy can neither be created and nor be destroyed but can be transformed from one form to another.

Now talking about your example in a typical light bulb electrical energy is converted into light energy and heat energy. Now when the electric current flows through the conductor/filament in the light bulb,this would cause vibrations and the free ions are more likely to go to an higher energy level,and when the ions come back to their original state,the difference in the two energy levels is usually emitted as a photon,thus light energy is obtained and the heat energy is the energy dissipated as a result of flow of electricity through the conductor.

Anything that gets transformed into light energy or in better words ElectroMagnetic Energy would be a result of this.

Use the Bohr-Rutherford model of the atom to explain how an insulator-differs from a conductor
GaryK [48]

Answer:

A conductor is a material that permits electrons to effortlessly go through it. Copper is a good conductor. Note that the valence shell has just a single electron.

While;

Materials that don't conduct are named insulators.(i.e. glass, porcelain, plastic, elastic. The covering on electrical wire is an insulator.)

Insulators don't conduct since they have a full or almost full valence shell and along these lines their electrons are firmly bound.

Explanation:

According to Bohr Rutherford model of Atom, An Atom contains three essential particles; Protons and neutrons that make up the nucleus and the electrons that circle or orbit the nucleus. The electrons circle the nucleus.

The laws of electrostatics predict that protons will
GaryK [48]
The laws of the electrostatics were developed by Coulomb and are further detailed or subdivided into two as follows:

(1) The first one talks about the similarities in the charges of the particles and what happens to them. This states that like charges repel.

(2) The second one quantifies the field between two particles with equation showing that field is directly proportional to the masses and inversely to the square of the distance between them.

In this item, we can then say that the protons (having the same charges) will have to repel from each other in accordance to statement 1 of the law.
