A helium-filled balloon at 1.00 atm pressure has a volume of 1.280 L. It is placed in a freezer and its volume decreases, stopping at 1.000 L. (Assume that the static internal and external pressures are equal, that the balloon contains only helium, and helium behaves as an ideal gas.)
- Calculate ΔE for the gas in the balloon.

i think so it’s will be b yes i believe its

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
