Energy Questions and Answers (Q&A)

There is no process that “gives” protons and other charged particles charge. They have charge, regardless of being protons, electrons or neutrons. It’s one of their defining properties. And because charge is (as far as we know) absolutely conserved, there is no process that can give a particle charge or take it away.


Protons, in the modern Standard Model of particle physics, are hadrons, and like neutrons, the other nucleon (particles present in atomic nuclei), are composed of three quarks. Although protons were originally are seen as elementary particles, they are now known to be made of three valence quarks: two up quarks of charge +2/3e and one down quark of charge –1/3e.


However, the rest masses of quarks contribute only about 1% of a proton's mass. The remainder of a proton's mass is due to quantum chromodynamics binding energy, including the quarks' kinetic energy and the energy of the gluon fields that bind the quarks together. Because protons are not elementary particles, they have a physical size, though not a definite one. A proton's root mean square charge radius is about 0.84–0.87 fm or 0.84×10−15 to 0.87×10−15 m.

The correct answer to this question is C, Electric to thermal. Electric toasters are used in many homes to make toast, waffles, and frozen pastries. A toaster transfers electric energy taken from the electrical outlet into thermal energy, which is heat.

In the toaster, there are filaments, also known as wires, which turn red. They do this because that is the heat which warms the toast, waffles, and pastries. These filaments get very hot and shouldn't be touched. While all toasters cook quickly, the higher the watt rating on the toaster, represents, the faster it can heat and cook the food.

HRV stands for Heat Recovery Ventilation. HRV works by removing stagnant air from a room that has higher humidity. It is commonly used in rooms that accommodate many rooms. It gives fresh outdoor air into the atmosphere. The heat recovery warms the incoming fresh air as the state air is expelled.


ERV stands for Energy Recovery Ventilation works similarly. It is commonly used in a cooler environment where there is no much humidity. The energy recovery recovers heat. It recuperates energy that is trapped in humidity. In summer, the humidity transfer works in reverse. The humidity in outdoor air is removed before it is allowed into the room.

Every day, the demand for energy keeps on growing as the population and usage of electricity increase to power our homes and gadgets. Sadly, most energy that we consume today is not renewable though there is an effort to use solar and hydro energy to sustain the people widely. Two of the most popular are coal and nuclear energy. Coal energy uses coal wherein a fossil fuel is burned to produce heat to produce energy.

To produce the energy needed, trucks carrying coals are required to deliver every day. Nuclear energy, on the other hand, uses enriched radioactive elements in the process of nuclear fission to produce heat. Due to radioactivity, most nuclear plants have more safety precautions to ensure the safety of the workers as well as the people. This is dangerous in the hands of terrorists; thus, nuclear power plants are safeguarded well.

Enthalpy is the heat relocation taking place in constant pressure, while entropy gives an idea of the randomness of a system. Enthalpy and entropy are two terms verifying the reactions taking place in a system. Enthalpy and entropy are thermodynamic state functions.

When a response takes place, it may absorb or evolve heat. Carrying out the reaction at continuous pressure is called enthalpy. Enthalpy is the heat transfer which takes place in a constant pressure. Enthalpy is the first law of thermodynamics; however, entropy is the second law of thermodynamics.

Enthalpy can be employed to measure the change in energy of the system after the reaction. We can use enthalpy to measure the degree of disorder of the system after the reaction.

The energy of a compound that changes as it atoms are rearranged to form new compounds

The answer to this is C. You need to remember that the movement of the small particles can cause heat. For example, when you bring water to a boil, water becomes hotter because the molecules of water keep on moving around until the boiling point is reached. This is the same with all the other types of matter that you can find in this world whether they are solid, liquid, or gas.

Temperature is the measurement of how hot or how cold the object is. Heat is known as the transfer of one hot molecule to a cold molecule so that it can also become hot. The thermometer is the device that you will use to measure the temperature.

C is the answer to this question. There are always some different types of power and energy that are being produced by people depending on the movement that they do. Take note that there are various factors that can also affect the amount of effort that people will place into the activities that they do.

There are different equations that people use in order to compute for power. Some examples are: V = I × R which is Ohm’s law equation. Another formula is P = I × V which is also known as the power law equation. It will depend on the circumstance which formula you will use.

The correct answer to this question is CO. CO is a compound of carbon and oxygen. A compound itself is a chemical that is formed from atoms that are taken from two different elements. Chemical bonds join the particles together. Their bond is so strong that they stick together and behave as one.

A chemical compound can be a liquid, solid, or a gas. CO is a gas. Another example is H20, which is a liquid. Compounds can be made naturally through plants or synthetically through a scientist, making them in a lab. When it is made synthetically, it is called synthetic chemicals.

Work is known to be the ability to do something. For example, when you try to lift something up from the ground, you are doing work. What you will use in order to do this type of work is energy. They actually go hand in hand together with the various things that you do.


Even when you are just working in front of your computer, you are using energy in order to think and decide what you are going to do next. Some say that they can be similar depending on the type of energy that you are referring to. Potential energy will be the same with work while kinetic energy will be the same with work that is already done.
