Answer:
its mass
its temperature
Explanation:
The heat capacity of a body is the amount of heat needed to raise that temperature of a body by 1k or 1°C.
It is expresses as:
H = m c Ф
where m is the mass of the body
c is the specific heat of the body
Ф is the temperature change of the body
Specific heat capacity is that heat content needed to raise the temperature of a unit mass of a substance by 1k or 1°C
Heat capacity is also known as heat content;
To solve the problem:
since H = m c Ф
we make the unknown c the subject of the expression;
c = = H / mФ
So to obtain the specific heat capacity, divided the heat capacity by mass and its temperature change.
Explanation:
An alpha particles is basically a helium nucleus and it contains 2 protons and 2 neutrons.
Symbol of an alpha particle is . Whereas a neutron is represented by a symbol
, that is, it has zero protons and only 1 neutron.
Therefore, reaction equation when an aluminum- nuclide transforms into a phosphorus- nuclide by absorbing an alpha particle and emitting a neutron is as follows.
