In terms of temperature, pressure and volume, what is happening when a hot air balloon inflates?

Explanation:

This means that when the gas in a hot air balloon is heated, the gas expands. The balloon has a fixed volume, but there is a hole at the bottom. So, the extra volume flows out of the hole in the bottom of the balloon. Since there is less air in the same volume, its density decreases

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
