A given mass of gas occupies 2dm3 at 300K. At what temperature will its volume be doubled keeping the pressure constant?
- A) 400K
- B) 480K
- C) 550K
- D) 600K
Correct Answer: D) 600K
Explanation
When a gas undergoes a change in temperature and volume with constant pressure, we can use Charles's Law to determine the relationship between the initial and final states of the gas. Charles's Law states that the volume of a gas is directly proportional to its temperature when the pressure is constant (V ? T).
Let's denote the initial volume as V1 and the initial temperature as T1. The final volume (V2) is double the initial volume (2V1), and we need to find the final temperature (T2).
Using Charles's Law, we can set up the following equation:
\[\frac{V1}{T1} = \frac{V2}{T2}\]Now plug in the given information: V1 = 2dm
