Part 3/9:
Various units measure pressure, with atmospheres being an illustrative choice, particularly for planetary contexts. At sea level, the pressure is one atmosphere, akin to the weight exerted by a large animal. Interestingly, our body naturally balances this external pressure, preventing discomfort even in high-pressure environments.
The Journey Through Different Pressures
Let's embark on a hypothetical journey from the outer reaches of space to the depths of the Earth, observing how different materials change under various pressure conditions.
