The first option, collapsed in on itself. The star's core mass becomes so dense that the resulting gravity implodes the star. Interesting enough, the third option is kindof true too...some large and tenacious black holes that absorb other stars will form incredibly bright accretion disks around their perimeter before filling absorbing the star.

Why does tire pressure change with temperature? Explain why the atoms are interacting in the certain way, How temperature plays

Wittaler [7]

The main reason behind this is Boyle's law and Gay Lussacs law

Gay Lussac's law states that Pressure is directly proportional to Temperature.
Boyle's law states that Volume is inversely proportional to pressure.

If temperature will be more Pressure will be more

Answer:

Explanation:

Given that:

The argon atoms are excited into an excited state before emitting the 488.0 nm laser.

the energy of the first ionization energy of argon is 1520 kJ mol-1.

SInce 1 eV = 96.49 kJ/mol

Therefore, the energy of the first ionization energy of argon in eV is = ( 1520/ 96.49) eV

= 15.75 eV

To find where the energy level of the excited state lies below the vacuum energy level, let's first determine, the energy liberated by using planck expression.

$E = \dfrac{hc}{\lambda}$
