Question

A gas sample in a closed, expandable container of initial volume 5.00 l was allowed to warm from 25 °c to 35 °c. What was its new volume, assuming the pressure and amount of gas do not change?

1) 4.84 l
2) 5.17 l
3) 7.00 l
4) 3.57 l
5) 4380 l

Answer 1

According to Charles' law, the new volume of the gas sample can be found using the equation V1/T1 = V2/T2. Plugging in the values given, the new volume is approximately 5.17 L.

Step-by-step explanation:

According to Charles' law, for a gas at constant pressure, the volume is directly proportional to the temperature in Kelvin. To find the new volume of the gas sample, we can use the equation:

V1/T1 = V2/T2

Where V1 is the initial volume, T1 is the initial temperature, V2 is the new volume, and T2 is the new temperature.

Plugging in the values given, we have:

5.00 L/298 K = V2/308 K

Solving for V2, we find that the new volume is approximately 5.17 L.
