In classical physics, matter is conserved. This means that the total mass of an isolated system remains constant over time. However, in certain situations involving nuclear reactions or particle-antiparticle annihilation, matter can be converted into energy according to Einstein's equation E=mc^2.
What else can I help you with?
When momentum can be conserved?
Momentum can be conserved when the total external force acting on a system is zero. In these cases, the total momentum of the system remains constant before and after the interaction. This principle is commonly observed in situations involving collisions, explosions, or interactions between objects.
Is matter and energy always constant?
According to the law of conservation of mass-energy, matter and energy are always conserved in a closed system. This means that while matter and energy can change forms or be converted into one another, the total amount of matter and energy in the system remains constant.
Must energy always be conserved?
According to the law of conservation of energy, energy cannot be created or destroyed, only transformed from one form to another. In isolated systems with no external influences, the total energy remains constant. So, yes, energy must always be conserved.
Is entropy always conserved in a closed system?
No, entropy is not always conserved in a closed system. Entropy can increase or decrease in a closed system depending on the processes happening within it.
Is mechanical energy always conserved Can you explain why or why not?
Mechanical energy is not always conserved. It can be converted into other forms of energy, such as heat or sound, through processes like friction or collisions. This means that the total amount of mechanical energy in a system may change over time, making it not always conserved.
When metamorphic rock melts and turns into lava is matter conserved?
Yes, this is a simple physical change and matter is always conserved in these. In fact, matter is always conserved except in nuclear reactions where the sum of matter and energy is conserved.
Is matter and energy conserved in a food web?
Matter and total energy are ALWAYS conserved. However, in a food web, you will often consider the USABLE energy; this gets reduced at each step of the food web.
When matter changes state what two things are always conserved?
When matter changes state, the amount of mass and the amount of energy are always conserved. This means that the total mass and energy of the system remain constant throughout the phase change.
When momentum can be conserved?
Momentum can be conserved when the total external force acting on a system is zero. In these cases, the total momentum of the system remains constant before and after the interaction. This principle is commonly observed in situations involving collisions, explosions, or interactions between objects.
Is machanical energy always conserved?
No. Total energy is always conserved, but not so mechanical energy.
Is mass conserved when nickel reacts chemically?
Yes. Basically, mass is always conserved.Yes. Basically, mass is always conserved.Yes. Basically, mass is always conserved.Yes. Basically, mass is always conserved.
Is matter and energy always constant?
According to the law of conservation of mass-energy, matter and energy are always conserved in a closed system. This means that while matter and energy can change forms or be converted into one another, the total amount of matter and energy in the system remains constant.
When metamorphic rock melts and turns into lava, is conserved?
matter
Where is linear momentum conserved?
Inertia of matter.
When electric charge is conserved?
Always
Mechanical energy always conserved why or why not?
no it's not cuz if there is friction energy wont be conserved
When you throw a matter from a height why mechanical energy is not conserved?
When you throw matter from a height, mechanical energy is not conserved by you, but it is by the matter. You are exerting mechanical energy to throw the object, and the matter is conserving it by not having to do any work to move.
