True. Gamma ray emission involves the release of high-energy photons from the atomic nucleus without changing the mass or nuclear charge of the emitting atom.
Mass is conserved during any change in color, volume, identity, or physical state. This principle, known as the law of conservation of mass, states that matter cannot be created or destroyed in a chemical reaction, only rearranged.
When fuel is burned, its mass does not change. The conversion of fuel to energy during combustion involves a rearrangement of atoms and molecules, but the total mass remains constant according to the law of conservation of mass.
Stoichiometry can be used to calculate the energy absorbed when a mass melts by considering the enthalpy of fusion, which is the amount of energy required to change a substance from solid to liquid at its melting point. By using the molar mass of the substance and the enthalpy of fusion, you can calculate the amount of energy needed to melt a specific mass of the substance.
False
It states that energy can change but mass can not change Chuma.C
It doesn't really have to - there is no such thing as "mass-to-energy conversion", rather, a change in energy will be accompanied by a change in mass. But the change in mass sometimes simplifies calculations.
The change in potential energy is equal to mass*gravity*change in height
No, mass does not increase during a nuclear change. According to the principle of mass-energy equivalence (E=mc^2), the mass of the reactants is converted into energy during a nuclear change.
It destroys mass to release energy
The maximum energy conversion from gravitational potential energy to kinetic energy occurs when all of the initial potential energy of the mass is converted to kinetic energy. This means that the maximum amount of energy the mass can change from gravitational potential energy to kinetic energy is equal to the initial potential energy of the mass.
Gamma decay involves only the release of high-energy photons and does not change the mass of the radionuclide. Gamma decay occurs when an excited nucleus releases excess energy in the form of gamma rays while remaining in the same nuclear state.
The total amount of mass-energy in a closed system cannot change. Energy can change from one form to another, Mass can change from one form to another, Energy can change to Mass, or Mass can change to Energy; but the total must remain constant. Since Mass and Energy are traditionally measured in different units, we need a units conversion equation to tell us how much of each has changed to the other to get the equations right. Einstein provided us with that from his Special Relativity: E = Mc2
Kinematics
Kinetic energy depends on mass, and speed. Since you can't easily change an object's mass, you would basically change its speed.
True. Gamma ray emission involves the release of high-energy photons from the atomic nucleus without changing the mass or nuclear charge of the emitting atom.
Energy can cause a change in the motion, temperature, or chemical composition of an object, but it does not have mass or volume itself. It is a property of objects and systems that can be transferred or converted into different forms.
