Why law of conservation of mass should better be called as law of conservation of mass and energy?

Because energy can be converted into mass and vice versa. Thus, while the mass of a system is not conserved in a particular process, the mass and energy of a closed system is always conserved.

Is activation energy added or just there?
Activation energy is the amount of energy that should be gained by potential reactants, for a reaction to occur. A reaction can be occurred by reducing the activation energy of the reaction or increasing the activation energy of the reactants. Activation energy should be added.
Which alternative energy source do you think should developed in the future explain.?
I consider that the nuclear energy is a chance for the future.
Define the term of forest conservation?
Forest Conservation has two possible meanings. The first is the view that (some) forests should not be interfered with by man in any way. This does not really fit the definition of conservation however. The second I will quote from the Sustainable Forestry Initiative and the father of American Forestry Gifford Pinchot.
Is geothermal energy efficient?
Geothermal heat pumps boast a high energy efficiency. According to the U.S. Environmental Protection Agency (EPA), geothermal heat pumps are the most energy-efficient, environmentally clean, and cost-effective systems for temperature control. If you have any question of geothermal energy you should visit http://geothermalexpert.net/index.html and do some research. It's never been a better time to invest in living green!
How does the law of conservation of mass relate to photosynthesis and respiration chemical equations?
The law of conservation of energy states that the amount of energy in a closed system is the same. The earth isn't a closed system, as the sun's radiant energy is constantly beaming down and heat is constantly seeping out of the atmosphere. Plants gain energy from the sun and then use that energy to create their own food.
Who are the people that should practice conservation?
All people should practice conservation of energy, water, paper, transportation, ... etc for the benefit of environment and future generations.
What is energy conservation and why should citizens conserve energy?
Energy conservation is that energy cannot be created or destroyed it can be transferred or transformed. We conserve energy no matter what we do. What we are really being told is to conserve usable energy which is energy not in the form of heat. We are told this to avoid the heat death of the universe this is when all the usable energy is lost due to heat.
Slogans on electricity conservation?
Think Green and save electricity.
What are the important application of law of conservation of energy?
For a start, it tells you that any effort to get energy "for free" (create energy where there was none before) are doomed to failure. In general, the Law of Conservation of Energy helps understand many physical situations; some calculations can be done quite simply if you assume (as you should) that energy is always conserved.
What are the important concept that the teacher is emphasizing energy transformed?
One concept in energy transformations that everybody should understand is conservation of energy. The total amount of energy always remains constant. No new energy is created, and no energy is destroyed.
What are the law of conservation of matter?
to save energy u should; -do not over work your body -do not over work equipments -use adapters to break down the amount of energy used -plug out equipments when not in use
Is a detection of decrease in the mass of salt a violation of the law of conservation of mass?
Your salt may have decreased in mass, but the sodium and calcium that made it still exist. They have gone into another form - probably dissolved in water. Or maybe just blown away. You should also note that conservation of mass goes hand in hand with conservation of energy, as mass and energy are themselves interchangeable. This is the meaning of Einstein's famous equation, E = mc2
What is the conservation?
That may refer to several unrelated concepts, mainly:* Conservation laws in physics, meaning that some amount doesn't change over time (for example mass, energy, electric charge, momentum, and several others) * Caring for something, so that it isn't wasted or destroyed, for example, "we should conserve water", or "environmental conservation".
Explain why the law of conservation of energy means that we do not have unlimited source of energy?
Answer: The law of conservation of energy means that we do not have unlimited energy because there is a finite amount of energy in the universe, it is merely converted into other forms of energy or matter. Answer: Actually there are two important energy laws - the First and Second Law of Thermodynamics. You should understand both of them to understand what goes on in our Universe, with respect to energy. The First Law (= Conservation of Energy) means that no new energy can be created (or destroyed, for that matter). We can use whatever energy is available in the Universe, but we can't create any new energy. Thus, the total amount of energy in the Universe is limited. The Second Law states that useful energy is constantly being converted into unusable energy. Thus, even though energy can't be destroyed, it will eventually get "used up" in the sense that it is no longer usable. As a result of this, the total amount of energy in the Universe is limited.
Who is the scientist of law of conservation of energy?
This law evolved gradually over time, as more types of energy were found to be interchangeable. No single scientist can be credited with the discovery of this law. A special mention should be made of Emily Nöther - today, the Law of Conservation of Energy is derived from Nöther's Theorem. However, the Law was well-known, as an experimental fact, before Nöther's time.
When a moving object with momentum collides with another moving object with momentum what formula do I use?
If the two bodies form a closed and isolated system (that is no other external forces act on the system apart from the forces that the bodies exert on each other and no mass is allowed to enter or leave the system), the principle of conservation of momentum SHOULD be used. Remember: As long as the condition in the brackets above hold, the principle of conservation of momentum holds. Next, depending on the nature of the collision, another conservation law can be used. If the collision is perfectly elastic, then kinetic energy is conserved. Note that although kinetic energy is not always conserved, TOTAL energy is ALWAYS conserved. You could still apply the principle of conservation of energy for an inelastic collision provided you knew the amount of energy converted to other forms of energy.
Explain the laws of conservation of energy in your own words?
The total energy in a lone system remains consistent, energy isn't able to be eradicated or processed.
