Why boiling point and physically state of haloge ns and noble gases increases down the group?

The efect of dispersion forces increases with the number of electrons. As you go down the halogen group the number of electrons (2 X atomic number) is
F2 18e gas bp 85K
Cl2 34e gas bp 239 K
Br2 70e liquid bp 332 K
I2 106e solid bp 457K
The trend is is similar for the noble gases although as these are monoatomic the number of electrons does not increase that quickly.

How do the boiling points of the noble gases change as you go down?
The boiling points of noble gases increases down a group.
How do boiling points of the noble gases change as you go down the group?
Down the group generally boiling point increases. And this is true in the case of noble gases or group 18 also.
Why boiling point of noble gases increase down in the group?
The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
All gases become liquids when cooled to their what point?
Boiling point
Why are substances with low boiling point gas?
well these substances turn into gases very easily boiling turns liquid into gas, and with a low boiling point, this means it doesn't take much heat to make that substance a gas (they may even be gases at room temperature)

The solubility of gases do what as temperature increases?
The solubility of gases decrease as temperature increases.
What effect does temperature have on gases?
it increases the volume of the gases
Do gases have a low boiling point?
yes
Does boiling water contain any gasses?
it contain gases cause of the minerals coming from the boiling water

What happens to the solubility of gases as the temperature increase?
solubility generally increases with a temperature increase
How do you compare and contrast liquids solids gases?
you compare it by finding the boiling point firstyou compare it by finding the boiling dick
All gases become liquids when cooled to their what point?
Boiling point
What is the effect of temperature on the viscosity of gases?
For liquids; Viscosity tends to fall as temperature increases. For gas; Viscosity increases as temperature increases.
