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

A. 15.3cm³
B. 87.3cm³
C. 552.0cm³
D. 97.0cm³

Correct Answer:

Option D – 97.0cm³

Explanation

(V1/T1) = (V2/T2)
T1 = 3+273 = 276K
∴ (92/276) = (V2/291)
T2 = 18 + 273 = 291K
V2 (92 X 291)/276
= 97.0 cm³
