A gas has a volume of 546 cm3 at OºC. What is the volume of the gas at -100ºC if its pressure remains constant?
-
346cm3
- 446cm3
- 546cm3
- 646cm3
- 746 cm3.
The correct answer is: A
Explanation
\(\frac{V_1}{T_1} = \frac{V_2}{ T_2}\)
\(T_1\) = 0 + 273 = 273K, \(T_2\) = -100+273 = 173K
\(\frac{546}{273} = \frac{V_2}{ 173}\)
\(V_2 = 346cm^3\)
