In theory, according to the Theory of Relativity, matter has an equivalent energy, that can be calculated as E = mc2. That is, a kg. of matter has an energy equivalent of 9x1016 joules.

This doesn't mean that all that energy can actually be converted, but in some cases it can - for example, when matter collides with antimatter, it all gets converted to energy.

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.


What energy is the total energy of all of the particles in an object always flows from warmer matter to cooler matter?

The total energy is thermal energy, which is the sum of the kinetic and potential energies of all particles. This flow of energy from warmer to cooler matter is due to the second law of thermodynamics, which states that heat naturally flows from higher temperature regions to lower temperature regions until thermal equilibrium is reached.


How is the energy distributed in the universe?

The energy in the universe is primarily distributed across three main components: dark energy, dark matter, and ordinary matter. Dark energy, which comprises about 68% of the universe's total energy content, is thought to drive the accelerated expansion of the universe. Dark matter accounts for about 27% and plays a crucial role in the structure formation of galaxies and galaxy clusters. Ordinary matter, including stars, planets, and interstellar gas, makes up only about 5% of the total energy density, highlighting the dominance of dark components in cosmic energy distribution.


What is the total organic matter in an ecosystem?

Total organic matter in an ecosystem can vary greatly depending on the ecosystem type and location. It includes living organisms (plants, animals, microorganisms) as well as decaying organic material like dead plant matter and soil organic matter. The total organic matter is essential for nutrient cycling, energy flow, and ecosystem functioning.


Are ecosystems transformers of matter and energy?

In an ecosystem the reactions going on are chemical reactions, and the total weight of the substances involved remains constant. Matter is only destroyed in nuclear reactions such as the fission of uranium, which does not happen in a normal ecosystem. Energy is transformed though, for example the sun's energy is absorbed by plants making them grow.

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.


Energy related to motion or position of matter is?

Kinetic energy relates to the motion of matter, while potential energy refers to the position of matter in a given system. Together, these two forms of energy make up the total mechanical energy of a system.


What is the total amount of energy resulting from the movement of molecules in a body of matter?

The total amount of energy resulting from the movement of molecules in a body of matter is known as thermal energy or heat energy. It is a form of kinetic energy due to the motion of particles within the substance and is typically measured in joules.


What does the law conservation of what is matter and energy?

The law of conservation of matter and energy states that matter and energy cannot be created or destroyed, only transformed from one form to another. This means that in any chemical reaction or physical process, the total amount of matter and energy remains constant.


What is the total amount of energy possess by the movement of molecules in matter?

heat.


What does conseervation of energy mean?

Conservation of energy means that the total energy of a system remains constant no matter what the internal changes are.


Can matter and energy enter and exit a closed system?

No, in a closed system, matter and energy cannot enter or exit from the surroundings. The total amount of matter and energy remains constant within a closed system according to the law of conservation of mass and energy.


What happens to matter and energy and closed system?

In a closed system, neither the energy or matter changes. (Study Island)


What does the conservaton suggest about the conservation of energy the conservation of matter and the conservation of momentum?

Conservation laws suggest that energy, matter, and momentum cannot be created or destroyed but can only change forms or be transferred between objects. Conservation of energy states that the total energy in a closed system remains constant. Conservation of matter indicates that the total mass in a closed system is constant. Conservation of momentum asserts that the total momentum of an isolated system remains constant in the absence of external forces.


The total energy of the particles that make up any matter is?

The total energy of the particles that make up any matter is the sum of their kinetic energy (due to motion) and potential energy (due to interactions). This includes the energy associated with the particles' mass as well, as described by Einstein's equation E=mc^2.
