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
Answer:
-219
Explanation:
1.5(339) - 1.5(485) = -219
Answer:
12.084 lb
Explanation:
1 gram = 0.00220462 lb
multiply number of grams by 0.00220462
Ex. 2000 g x 0.00220462 = 4.409 pounds
