What does external energy mean?
External energy refers to energy that comes from sources outside of a system. This energy can be transferred to or from the system, impacting its overall energy level or ability to perform work. Examples of external energy sources include mechanical work applied to a system or heat transferred to or from the system.
What does it mean to say energy is conserved within a system?
When an object is accelerated along a distance that requires energy. If the object is then slowed to a stop by a breaking system that gets back that energy then the energy is said to be conserved
What does the the phrase energy is conserved mean?
The phrase "energy is conserved" means that the total amount of energy in a closed system remains constant over time. Energy can change forms or be transferred between objects within the system, but the total energy within the system remains the same.
What does it mean whenever energy appears in one system?
When energy appears in one system, it implies that the system has gained energy from an external source or undergone a process that has led to an increase in its energy content. This can manifest as physical changes, increased motion of particles, or a rise in temperature, depending on the nature of the system and the form of energy involved.
What does finite energy mean?
Finite energy means that there is a set amount of energy available in a system, and it cannot be created or destroyed, only transferred or converted into different forms. This concept is governed by the principle of conservation of energy, which states that the total energy in a closed system remains constant over time.
Is the heat content of a system at a constant pressure?
Yes it is possible, for example when water freezes there is a point when the temperature remains constant however energy is released as the water condenses.
What is the enthalpy of a reaction?
The amount of energy that is used or released as heat in a reaction.
What does positive enthalpy mean?
Positive enthalpy means that energy is absorbed from the surroundings during a process. This usually indicates an endothermic reaction where heat is taken in. For example, when ice melts into water, it absorbs heat from its surroundings, resulting in a positive enthalpy change.
What does ek mean in science?
big E little k Ek is the kinetic Enthalpy of a reaction
What dose triangle H soin mean in cemistry?
In chemistry, a triangle symbol (∆) typically represents a change in a system. For example, ΔH represents a change in enthalpy, which is a measure of heat energy in a chemical reaction.
What is the mean bond enthalpy of nitrogen?
The mean bond enthalpy of a nitrogen-nitrogen bond is approximately 945 kJ/mol.
How does the nervous system relate to the Immune System?
It Doesn't.... What do you mean it doesn't?all the systems interact together?
How do you know if an enthalpy change diagram is endothermic or exothermic?
If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.
What is systemic energy?
If you mean a system energy or an energy of a system, than in physics this means the sum of all different energies, of all parts of an observed system (part of bodies etc.).
What does external energy mean?
External energy refers to energy that comes from sources outside of a system. This energy can be transferred to or from the system, impacting its overall energy level or ability to perform work. Examples of external energy sources include mechanical work applied to a system or heat transferred to or from the system.
How is energy relate to magnetic?
I think what you mean to ask is, how do electricity and magnetism relate. well, electricity and magnetism combine in our universe to form what is known as electromagnetism, which the force that surrounds our Earth in deflecting solar radiation!
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.
