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.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
