A gas sample in a closed, expandable container of initial volume 5.00 L was allowed to warm from 25 °C to 35 °C, at constant moles and pressure. What was its new volume?
A)4.84 L
B)5.17 L
C)7.00 L
D)3.57 L
E)4380 L

According to Charles's Law, at constant pressure, the volume of a gas is directly proportional to its temperature (in Kelvin). Therefore, if the temperature increases from 25 °C (298 K) to 35 °C (308 K), the volume should increase in the same ratio. The new volume can be calculated as:
new volume = (initial volume) x (new temperature / initial temperature) = 5.00 L x (308 K / 298 K) = 5.17 L
Thus, choice B is the correct answer.
