Lower temperature
Let's verify
- Pressure=P
- volume=V
- Temperature=T
As per Boyles law
As per Charles law
So
At higher altitudes lower the pressure so lower the temperature
Explanation:
The emission of a beta particle is the result of the rearrangement of the unstable nucleus of the radioactive atom in order to acquire stability. For that, a phenomenon occurs in the nucleus, in which a neutron decomposes giving rise to three new particles: a proton, an electron (β particle), and a neutrino. The antineutrino and electron are emitted. The proton, however, remains in the nucleus.
The symbol is used to represent beta particles.

Answer: B. 5
Explanation: A neutral atom has equal number of electrons and protons.
Whenever a neutral atom loses electron it acquires a positive charge. Thus in order to acquire 3+ charge, it must lose three electrons. Thus the number of protons exceeds the number of electrons.
Thus the number of electrons left will be (8-3) = 5 electrons.
If an atom gains electrons, it acquires a negative charge and the number of electrons exceeds the number of protons.
