Question

a gas at 20℃ is heated till pressure triples and the volume increases by 2/5 of its original volume.calculate the final temperature

Answer 1

T(initial) =20°C=293
P(initial) =P
V(initial) =V
P(final) =3P
V(final) =0.4V
SO,
{P(initial) *V(initial) }/T(initial) ={P(final) *V(final) }/
T(final)

P*V*1/293=3P*0.4V*1/T(final)

therefore,
T(final) =3*0.4*293=351.6K
