Answer:

Volume = 966.66666 cm³

Explanation:

From all the gas laws we get,

PV = nRT

P = \dfrac{nRT}{V}

V

nRT

Therefore,

P ∝ \dfrac{T}{V}

V

T

or

\dfrac{PV}{T}

T

PV

= constant

Using the above eqution we get,

\dfrac{P_1V_1}{T_1}= \dfrac{P_2V_2}{T_2}

T

P

From the question we get,

P₁ = 725 mm Hg P₂ = 792 mm Hg

V₁ = 572 cm³ V₂ = ?

T₁ = 130° C T₂ = 240° C

Substituting all theses values we get,

\dfrac{725 \times 572}{130} =\dfrac{792 \times V_2}{240}

130

725×572

=

240

792×V

2

\dfrac{725 \times 572 \times 240}{130 \times 792} =V_2

130×792

725×572×240

=V

V_2 = 966. \bar6V

=966.
