A gas has a volume of 546 cm3 at OºC. What is the volume of the gas at -100ºC if its pressure remains constant?
A
346cm3
B
446cm3
C
546cm3
D
646cm3
E
746 cm3.
Verified Correct Answer: A.
Physical Principles & Numerical Solution
\(\frac{V_1}{T_1} = \frac{V_2}{ T_2}\)
\(T_1\) = 0 + 273 = 273K, \(T_2\) = -100+273 = 173K
\(\frac{546}{273} = \frac{V_2}{ 173}\)
\(V_2 = 346cm^3\)
