Explanation:

Beta decay:

Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.  In beta positive decay proton is converted into neutron and positron, thus the atomic number is decreased by one.

¹¹₆C → ¹¹₅B + ⁰₊₁e

In beta minus decay the one electron is ejected and neutron is converted into proton.

¹⁴₆C → ¹⁴₇N + ⁰₋₁e

Properties of beta radiations:

The mass of beta particle is smaller than the alpha particles.

They can travel in air in few meter distance.

These radiations can penetrate into the human skin.

The sheet of aluminium is used to block the beta radiation .

- decrease the number of plants and animals living in the water.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
