Answer:
as molecular mass increases, more molecules have speeds close to their average speed.
Explanation:
A plot of the Maxwell distribution of velocities for several different gases measured at the same temperature shows that "as molecular mass increases, more molecules have speeds close to their average speed."
This is evident in the fact that the Maxwell distribution of speeds for a given selection of gas at a given temperature shows certain traits if one of the main variables is changed, such as
1. Mass: The proportion of speeds for a given selection of gas is narrower and the average speed is lower for gas of higher molecular weight.
2. Temperature: The proportion of speeds for a given selection of gas is wider and the average speed is higher as the temperature of a gas increases.

How does warmer planet causes ice to melt and then cause the warm up even more?
Answer:
Melting ice causes more warming.
Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the heat to the atmosphere. This causes more global warming. In this way, melting ice causes more warming and so more ice melts.

26. Which compound, chloroacetic acid or iodoacetic
acid, most likely has the lower boiling point, and
why?
(A) Chloroacetic acid, because the London
dispersion forces among its molecules are
weaker
(B) Chloroacetic acid, because the dipole-dipole
forces among its molecules are weaker.
(C) Iodoacetic acid, because the London
dispersion forces among its molecules are
stronger.
(D) Iodoacetic acid, because the dipole-dipole
forces among its molecules are stronger.
The london dispersion forces are stonger in iodoacetic acid than chloroacetic acid making chloroacetic acid to have a lower boiling point.
What are london dispersion forces?The London forces are forces are intermolecular forces that act on compounds depending on the size of the molecule.
We must note that iodoacetic acid is a larger molecule than chloroacetic acid hence the london dispersion forces are stonger in iodoacetic acid than chloroacetic acid making chloroacetic acid to have a lower boiling point.

A balloon filled with helium has a volume of 30.0 L at a pressure of 100 kPa and a temperature of 15.0 C. What will the volume of the balloon be if the temperature is increased to 80.0 C and the pressure remains constant? (Hint: Use the Charles law equation)
Answer:
The final volume of the balloon is 24.480 liters.
Explanation:
Let consider that no leakages occur in the balloon during the isobaric process and that helium behaves ideally. From Equation of State for Ideal Gases, we construct the following relationship:
[tex]V_{o}\cdot T_{o} = V_{f}\cdot T_{f}[/tex] (1)
Where:
[tex]V_{o}[/tex], [tex]V_{f}[/tex] - Initial and final volume, measured in liters.
[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Initial and final temperature, measured in Kelvin.
If we know that [tex]V_{o} = 30\,L[/tex], [tex]T_{o} = 288.15\,K[/tex] and [tex]T_{f} = 353.13\,K[/tex], the final volume of the balloon is:
[tex]V_{f} = \frac{V_{o}\cdot T_{o}}{T_{f}}[/tex]
[tex]V_{f} = 24.480\,L[/tex]
The final volume of the balloon is 24.480 liters.
Convection currents slowly move tectonic plates across Earth

What does AS> O mean?
AS> 0 mean the system has become more random. This means that there is increase in entropy.
What is entropy?Entropy, in the realm of thermodynamics, quantifies the level of chaos or unpredictability within a system. A system characterized by heightened entropy exhibits greater disorder, whereas a system marked by diminished entropy reflects a higher degree of organization.
When AS > 0, it signifies an increase in the entropy of the system. This denotes a shift toward increased disorder or randomness within the system.
