Agas occupies 0.67 l at 350 k. what temperature is required to reduce the volume by 45%?

193.3 K

Explanation:

Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

   (At constant pressure and number of moles)

where,

= initial volume of gas = 0.67 L

= final volume of gas =

= initial temperature= 350 K

= final temperature = ?

Now put all the given values in the above equation, we get the final pressure of gas.

Therefore, the temperature required would be 193.3 K

c is the answer because when something is left after something evaporates that shows the chemical change.
