Answer:
the molecules of each substance attract each other through dispersion (London) intermolecular force.whether a substance is solid, liquid or gas depends on the balance between the kinetic energies of the molecules and their intermolecular attractions.
thank you.
Electronegativity.
Electronegativity can be defined as the measure of affinity of the element towards electrons . Higher the affinity towards electrons higher the electronegativity.
Eg : Fluorine has a high electronegativity. This is because it has 7 valence electrons, to gain a noble gas configuration / complete outer shell it needs to gain one electron. Hence the positive nuclear charge of the nucleus will attract an electron so it can become a complete outer shell , therefore F is very reactive.
Higher the attraction of the nucleus to electrons , higher its affinity therefore higher electronegativity.
Assuming the balloon initially has volume of 0 when deflated, the total P(deltaV) = (1.00 atm)(550,000 ft^3) = 550,000 atm-ft^3. To convert into work units, we can first convert ft^3 to L:
(550,000 atm-ft^3)(1 m/3.28 ft)^3
= (15,586.2 atm-m^3)
Then we convert to L:
(15,586.2 atm-m^3)(1000 L/m^3)
= 15,586,200 atm-L
Then we convert to J:
(15,586,200 atm-L)(101.325 J / 1 atm-L)
= 1.579 x 10^9 J

Answer:
The speed is constant.
Explanation:
The equation for a straight-line graph is
<em>y</em> = m<em>x</em> + b
where m and b are constants.
m is the <em>slope</em> of the line and b is the <em>y-intercept.
</em>
If we change the variables, the equation becomes
<em>d</em> = m<em>t</em> + b
Since m is constant, so is the speed.
