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

The correct answer is D. 97.0cm3

\(\frac{V_{1}}{T_{1}}\) = \(\frac{V_{2}}{T_{2}}\)

\(T_{1}\) = 3 + 273 = 276K

\(T_{2}\) = 18 + 273 = 291K

\(V_{1}\) = \(92cm^{3}\)

\(V_{2}\) = ?

\(V_{2}\) = \(\frac{V_{1}T_{2}}{T_{1}}\)

=\(\frac{92 \times 291}{276}\) 

= \(97.0cm^{3}\)
