Answer:
The final volume of the balloon is = 28.11 L
Explanation:
Initial pressure = 1.03 atm = 104.325 K pa
Initial temperature = 26 °c = 299 K
Initial volume = 22.4 L
Final temperature = 22 °c = 295 K
Final pressure = 0.81 atm = 82 K pa
We know that
Put all the values in above formula we get
= 28.11 L
This is the final volume of the balloon.
Psychical(you see the changes visible) and Chemical properties(they react and combine, you may see fizzing or bubbles).
boiling, salt water will separate the salt from the water through the physical change of water from a liquid to a gas, leaving you with just salt left over.
