Answer:

1.8dm3

Explanation:

we use the formulae

(p1*v1)/t1=(p2*v2)/t2

since we are looking for volume 2 we make v2 subject of formula

p2=(p1*v1*t2)/v2*t1

where p1=1

t1=25+273=298

v1=1.5

t2=100+273=373

p2=1

inputting our values we have

(1*1.5*373)/1*298

559.5/298=1.8

1.8dm3

Pressure is constant

So convert temperatures into Kelvin

  • 25°C=298K
  • 100°C=373K

Apply Charles law

  • V1T2=V2T1
  • 1.5(373)=298V2
  • 559.5=298V2
  • V2=1.88dm³
