A gas has a volume of 27.3 c.c. at 0°C. Its volume at 10°C (if pressure remains unchanged) will be _____________ c.c?
Correct answer: B. 28.3
- A. 2.73
- B. 28.3
- C. 273
- D. 283
Explanation
At constant pressure, Charles's law gives V₂/V₁ = T₂/T₁ using absolute temperature. Thus V₂ = 27.3 × 283/273 ≈ 28.3 cc, not 27.3 × 10.
