Question

A gas sample occupies 4.39 L at 44 °C. What will be the new volume, using Charles' Law, if the temperature decreases to 25 °C?

a) 7.73 L
b) 2.49 L
c) 4.66 L
d) 4.13 L

Answer 1

To find the new volume using Charles' Law, we can use the equation: V1/T1 = V2/T2. Given the initial volume and temperature, we can convert the temperature to Kelvin and solve for the new volume. The new volume will be 4.13 L.

Step-by-step explanation:

To find the new volume using Charles' Law, we can use the equation:

V1/T1 = V2/T2

Given that the initial volume (V1) is 4.39 L and the initial temperature (T1) is 44 °C, we need to convert the temperature to Kelvin:

T1 = 44 + 273 = 317 K

We can then solve for the new volume (V2) using the equation:

4.39 L / 317 K = V2 / 298 K

By cross-multiplication, we find:

V2 = (4.39 L * 298 K) / 317 K = 4.13 L

Therefore, the new volume, using Charles' Law, will be 4.13 L (option d).
