Answer:
The pressure the hydrogen gas exerted before its volume was decreased is 2.7207 atm.
Explanation:
Using Boyle's law
Given ,
V₁ = 14.65 L
V₂ = 7.94 L
P₁ = ?
P₂ = 5.02 atm
Using above equation as:
<u>The pressure the hydrogen gas exerted before its volume was decreased is 2.7207 atm.</u>

Commonly the sea walls are used for preventing damage from tsunami. A special type of device is also used for detecting the tsunami called floating device.
<h3>
What are the technologies that could help reduce the damage from a tsunami?</h3>
Commonly seawalls are used for preventing damage from tsunamis. There is a network which is used for detecting the earthquake and tsunami and that network is known as Seismological network. This network helps the people to know about the earthquakes and tsunamis and reduces the damages of earthquakes and tsunamis.
The engineers also design a special type of special buoys which is also known as floating devices, these devices are placed near the coastal areas from where the tsunamis can be detected easily.
So we can conclude that commonly the sea walls are used for preventing damage from tsunami. A special type of device is also used for detecting the tsunami called floating device.
