Question 1

What is a terapascal?

Accepted Answer

1 TPa = 10¹² Pa = 1000 GPa = 10 million bar. Found in stellar interiors and high-energy physics.

Question 2

What has terapascal pressure?

Accepted Answer

White dwarf cores (~1 TPa), supernova cores (100+ TPa), early universe conditions.

Question 3

What pressure units do different industries use?

Accepted Answer

PSI in US/UK automotive and HVAC. Bar/kPa in European engineering. mmHg/torr in medicine. Atmospheres in diving and altitude.

Question 4

Is gauge pressure different from absolute pressure?

Accepted Answer

Yes! Gauge pressure reads 0 at atmospheric pressure. Absolute pressure adds atmospheric (~14.7 psi). Vacuum gauge shows negative gauge pressure.
