A flexible container is charged with 30.00 L of gas at 313K.Under conditions of constant pressure and moles of gas,what is the volume of the gas when the temperature is decreased by a factor of two?
A) 15.0 L
B) 60.0 L
C) 0.0167 L
D) 30 L
E) 3.00 L

According to Charles's Law, when the pressure and moles of gas are constant, the volume of a gas is directly proportional to its temperature in Kelvin. Since temperature is decreased by a factor of two (from 313 K to 156.5 K), the volume of the gas will also decrease by a factor of two. Therefore, the final volume of the gas will be 15.0 L to two significant figures. Choice A is the only option that matches this result.
