Answer:
The new pressure is 44.4 kPa.
Explanation:
We have,
Initial volume, 
Initial pressure, 
It is required to find the new pressure when the volume is increased to 50 ml. The relationship between pressure and volume is known as Boyle's law.

is final pressure

So, new pressure is 44.4 kPa.

Number of second in human lives in scientific notation is 3.9 × 10⁷ second
<u>Given that;</u>
Average human lives = 74 years
<u>Find:</u>
Number of second in human lives in scientific notation
<u>Computation:</u>
Number of second in human lives in scientific notation = 74 × 365 × 24 × 60
Number of second in human lives in scientific notation = 38,894,400
Number of second in human lives in scientific notation = 3.9 × 10⁷ second

Answer:
79.04 L
Explanation:
We are given;
Initial Volume; V1 = 6.24L
Initial Pressure; P1 = 760 mm Hg
Final pressure; P2 = 60.0mm Hg
To solve for final volume, we will use Boyles law;
P1•V1 = P2•V2
Let's make V2 which is the final volume the subject;
V2 = (P1•V1)/P2
V2 = (760 × 6.24)/60
V2 = 79.04 L
