Answer: 7. The new temperature of the neon gas is 520 K.
8. The volume of the balloon when it’s placed in a freezer is 2.3 L.
9. The new volume of the gas is 1.25L.
10. The new volume is 0.07 L.
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)

= initial volume of neon gas= 680 ml= 0.68 L
= initial temperature =

= final volume of neon gas = 1.32 L
= final temperature = ?


8.

= initial volume of helium gas = 2600 ml = 2.6L
= initial temperature helium gas =

= final volume helium gas=?
= final temperature of helium gas =



9.

= initial volume of ammonia gas = 650 ml = 0.65L
= initial temperature helium gas =T K
= final volume helium gas=[ ?
= final temperature of helium gas =



10.

= initial volume =105 ml = 0.105 L
= initial temperature helium gas =

= final volume helium gas= ?
= final temperature of helium gas =
