Question

At constant pressure a balloon takes up 625L at 0° C . If it is heated to 80°C , what will be it's new volume. ​

Answer 1

Answer:

see the following pic....

Answer 2

Explanation:

We know that as constant pressure, and constant quantity of gas,

V∝T ..i.e. V=kT ...where k is some constant of proportionality.. But this should hold for ALL conditions of temperature. And so we solve for k ...and so

V1/T1=V2/T2 ; temperature is specified on the absolute scale.... 0⋅K≡−273.15∘C

And so

V2=V1/T1×T2=624⋅L/273.15⋅K×353.15⋅K ..

We gets

V2≅800⋅L ...
