What is water displacement?????

Answers

When you put an object in water it moved the water to make room for itself. It is used to measure

Water displacement was discovered by the Greek thinker Archimedes in the 3rd century BC. He worked out that if you put an object in water, the amount of water displaced (thrown out) is equal to the volume of that object. By measuring the overflow of water, you can work out the volume of the object (it only really works if the object is non-porous/ can't soak up the water. In fluid mechanics, displacement occurs when an object is immersed in a fluid, pushing it out of the way and taking its place. The volume of the fluid is displaced can then be measured.

What are the Respiration effects on the pH?

Answers

Our blood have a pH around the 7.0, when we hold the breath our cells still breathing, and the release $CO_2$ , this compound react with water (hydrolysis).

$H_2O+CO_2\leftrightharpoons H_2CO_3$

This compound formed by this reaction is acid, carbonic acid.

Them the pH will get lower them normal, and our buld send an action to our body, and this reaction will be the breathing.
