Answer:
The final volume is 1.6 L.
Explanation:
It is given that,
A diver has a lung capacity of 2.4 L when the pressure is 0.8 atm. We need to find the volume of the diver’s lungs when the pressure changes to 1.2 atm. Let V₂ is volume.
It is based on Boyle's law. According to this law,

K is constant


So, the final volume is 1.6 L.
An element or compound will react with oxygen and will produce carbon dioxide, water, and sometimes carbon (if it is an incomplete combustion).
Metals experience plastic
deformation when a specific amount of pressure and temperature is applied to
them. Most metals have low specific heat. Because of their low specific heat,
they easily get hot when heat is applied to them.
