Question

1. The volume of a gas is 10.0 liters and its temperature is 1500 K. If the temperature is

Answer 1

Answer:

5 L

Explanation:

So this problem refers to Charles's law. You would use this formula..

$\frac{V_{I} }{T_{I} } = \frac{V_{F} }{T_{F} }$   (Initial volume / Initial Temperature) = (Final volume / Final Temperature)

For your problem, it would look like this...

$\frac{10L}{1500k} = \frac{V_{F} }{750k}$

You would cross multiply and your answer would be 5L.

To reassure yourself that the answer is correct, Charles law states that the Volume and the Temperature are directly proportional. Meaning if your temperature is decreasing, your volume has to decrease.
