A fixed mass of gas occupies 92cm3 at 3°C. What will be its volume at 18C if the pressure remains constant?

A.

15.3cm³

B.

87.3cm³

C.

2.0cm³

D.

97.0cm³

View answer & explanation

Correct answer is D

$\frac{V_{1}}{T_{1}}$ = $\frac{V_{2}}{T_{2}}$
$T_{1}$ = 3 + 273 = 276K
$T_{2}$ = 18 + 273 = 291K
$V_{1}$ = $92cm^{3}$
$V_{2}$ = ?
$V_{2}$ = $\frac{V_{1}T_{2}}{T_{1}}$

= $\frac{92 \times 291}{276}$
= $97.0cm^{3}$
