<h3>
Answer:</h3>
812 kPa
<h3>
Explanation:</h3>
- According to Boyle's law pressure and volume of a fixed mass are inversely proportional at constant absolute temperature.
- Mathematically,
At varying pressure and volume;
P1V1=P2V2
In this case;
Initial volume, V1 = 2.0 L
Initial pressure, P1 = 101.5 kPa
Final volume, V1 = 0.25 L
We are required to determine the new pressure;
Replacing the known variables with the values;
= 812 kPa
Thus, the pressure of air inside the balloon after squeezing is 812 kPa
Should be 2Na + Br2 = 2NaBr :)

Answer:
Energy cannot be created or destroyed.
Explanation:
According to the law of conservation of energy, energy can neither be created nor it can be destroyed. Energy can only be transformed from one matter to another. The conservation of energy remains constant in an isolated system. The law is applicable in the system that does not exchange energy in the environment. Energy changes its form but remains constant.
