Agas in a balloon at constant pressure has a volume of 160 ml at -125*c. what is its volume at 29.0*c?

- 330 L

Solution:- At constant pressure, volume is directly proportional to the kelvin temperature.

where, is the initial volume at initial temperature and is the new volume at temperature .

From given info,

= 160 mL

  = -125 + 273 = 148 K

= 29.0 + 273 = 302 K

= ?

Let's plug in the values and solve this for new volume.

On rearrangement:

[tex]V_2] = 326 L

If we round the answer for two sig figs(as given in initial volume) then it will be 330 L.

So, the new volume of the balloon is 330 L.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
