Answer:
less dense
Explanation:
the reason that the density would be lower is because the air bubbles keep the maximum amount of atoms possible from being in that space. imagine pouring a glass of soda from a freshly opened bottle, at first it looks like there's a lot in the glass but as the bubbles dissipate, there's less and flat soda appears to have even less in the glass. i hope this analogy helped :)
Answer:
2080 kJ/mol is the first ionization of 1st atom and 496 kJ/mol is the first ionization of 2nd atom
Explanation:
Given electronic configurations are :
1st:
2nd :
given 1st ionization energy are: 2080 kJ/mol and 496 kJ/mol
generally ionization energy of fulfilled orbital is more than half filled orbital and these two state are more stable.
therefore ionization energy of fulfilled is more than half filled orbital
hence
ionization energy of 1st atom will be very high because its orbital is fulfilled and less energy for 2nd atom so 2080 kJ/mol is the first ionization of 1st atom and 496 kJ/mol is the first ionization of 2nd atom.
<u>The velocity and pressure of a fluid is related as follows:</u>
The speed is also called as velocity. Bernoulli’s Principle states that, higher the velocity of a fluid (means liquid or gas), the lower the pressure it exerts. The rapid motion of the fluid molecules causes the Fluid pressure. The Bernoulli equation is given as,
Where,
P – Pressure
ρ –density
v – Velocity
g – Gravitational acceleration
h - Elevation
So, when the fluid moves faster, some energy from the rapid motion of the fluid is used to move faster in the fluid’s direction of motion which results in a low pressure. Thus, the more the speed of a fluid, the lesser is the pressure ().
