Concept explainers
(a)
Interpretation:
The energy in joules corresponding to the destruction of the given matter needs to be determined.
Concept introduction:
The matter is converted from one form to another since it is neither created nor destroyed.
As a result of this process of conversion, large amounts of energy is generated.
Joules is the S.I unit for energy.
The energy transferred from one object is known as one joule of energy. This occurs when a force of one newton acts on the object in that direction.
(b)
Interpretation:
The energy in mega electron volts that would be released if one alpha particle were completely destroyed needs to be determined.
Concept introduction:
A fast-moving paticle which consists of two neutrons and two protons is an alpha particle. With a helium nucleus, they carry +2 charge and they strongly interact with matter.
1 mega electron volt or 1MeV is said to be equal to 1000000eV.
Electron volt or eV is the unit of energy.
One eV is said to be equal to
